6.1 Remapping Pins

The ESP32 features comprehensive pin remapping functionality. This allows peripherals to be mapped onto almost any available GPIO pins. The above table merely shows the default assignments. For example, the default mapping has the SPI and I2C clocks overlapping, meaning both cannot be used simultaneously without remapping one to a different pin. For a detailed guide of what peripheral can be assigned to what pins please read “Appendix A – ESP32 Pin Lists” of the ESP32 datasheet.

7.0 ESP32 Peripherals

Table 2 – Peripherals Figure 3 – External RTC crystal circuits † These are hardware limits, the micropython firmware may impose its own limits. * Requires an external CAN bus transceiver, we recommend the SN65HVD230 from Texas Instruments. For a more detailed description of the ESP32 peripherals along with peripherals not currently supported by our firmware, please check the ESP32 datasheet.

7.1 RTC

Our modules by default all use the internal RC oscillator at 150kHz for the RTC. If you require better accuracy/ stability you can connect a 32.768 kHz crystal (or TCXO) externally on pins P19 and P20 (or P19 for a TXCO) Peripheral Count Pins UART 3 Remappable to any GPIO. Note: P13–18 can only be mapped to RX or CTS since they are input only. I2C 2 Remappable to any GPIO except P13–18 since they are input only and I2C is bi–directional. SPI 3 Remappable to any GPIO. Note: P13–18 can only be mapped to MISO since they are input only. CAN* 1 Remappable to any GPIO. Note: P13–18 can only be mapped to RX since they are input only. JTAG 1 TDO = P4, TDI = P9, TCK = P10, TMS = P24 PWM 1 All GPIO except P13–18 which are input only ADC 18 Fixed mapping, see Table 1, Only ADC 1 is supported in our micropython firmware. DAC 2 Only available on P21 and P22 SD 1 DAT0 = P8, SCLK = P23, CMD = P4

8.0 Programming the device

8.1 UART

By default, the modules run an interactive python REPL on UART0 which is connected to P0 (RX) and P1 (TX) running at 115200 baud. Code can be run via this interactive REPL or you can use our PyMakr plugin for Atom or Visual Studio Code to upload code to the board.

8.2 Wi–Fi

By default, the W01 also acts as a Wi–Fi access point. . SSID: wipy–wlan–XXXX Password: www.pycom.io Once connected to the W01’s Wi–Fi network you can access it in two ways.

8.2.1 Telnet

Running on port 23 is a telnet server. This acts in a very similar way to the UART. It presents you with an interactive REPL and can also be used to upload code via PyMakr.

8.2.2 FTP

The W01 also runs a FTP server that allows you to copy files to and from the device, include an SD card if one is connected. To connect to this FTP server, you need to use plain FTP (un–encrypted) with the following credentials: User: micro Password: python

9.0 Boot modes

9.1 Bootloader mode

In order to update the firmware of the W01 device, it needs to be placed into bootloader mode. In order to do this, P2 needs to be connected to ground when the device reboots. Once in bootloader mode you can use the Pycom firmware update tool to update to the latest official firmware. If you are developing your own firmware based on our open–source firmware, a flashing script is provided with the source code.

9.2 Safe boot

The micropython firmware features a safe boot feature that skips the boot.py and main.py scripts and goes straight to the REPL. This is useful if the device is programmed with code that causes the device to crash or become inaccessible. To access this mode, you need to connect P12 to 3.3V and reset the device. Upon entering safe boot mode, the on–board LED will begin to blink orange. Depending on the duration the pin is held at 3.3V, a different firmware will be run. Table 3 – Boot modes 0–3 Seconds 3–6 Seconds Current firmware without running boot.py or main.py Previous firmware if the firmware was uploaded via OTA (without running boot.py and main.py)

10.1 Current consumption by power modes/features running at 3.7V

10.0 Power

The W01 features an on–board voltage regulator that takes 3.5V – 5.5V from the VIN pin and regulates it to 3.3V. It is important to only use the 3.3V as an output and not try to feed 3.3V into this pin as this could damage the regulator. Table 4 – Power consumption by feature* More details can be found in section 14.2 Mode Min Avg. Max Units Idle (no radios) – 34 – mA WiFi AP – 110 – mA WiFi client – 123 – mA Bluetooth – 107 – mA Deep sleep – 5.40 – μA

18.0 Design Considerations

18.1 Antenna Impedance

Our OEM modules are intended to be used with a 50–ohm antenna. They are also required to be connected to the antenna by a 50–ohm grounded co–planar waveguide (as shown in the reference design below with the yellow lines) or a microstrip.

18.2 Deep sleep power

When selecting a voltage regulator for your application ensure that it has a low power mode, and that this is enabled when the device enters deep sleep. We also recommend cutting off power to all non–essential components such as LEDs, logic gates, sensors etc. when the device is in deep sleep. This can be done using the circuit shown right: This circuit uses the 1.8V output of the module to cut off supply to non–essential circuitry. The 1.8V output is only active when the module is running, when it goes to deep sleep it drops to 0V. The non–essential circuitry is then powered from the “ACTIVE_POWER” bus. Figure 7 – 50–ohm impedance antenna connections Figure 8 – Power switch for deep sleep mode

23.2 Federal Communication Commission Interference Statement

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: – Reorient or relocate the receiving antenna. – Increase the separation between the equipment and receiver. – Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. – Consult the dealer or an experienced radio/TV technician for help.

23.2.1 RF Warning Statement

To comply with FCC RF exposure compliance requirements, the antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co–located or operating in conjunction with any other antenna or transmitter.

23.2.2 OEM integrator conditions

This device is intended only for OEM integrators under the following conditions: 1. The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2. The transmitter module may not be co–located with any other transmitter or antenna. As long as the two conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end–product for any additional compliance requirements required with this module installed. To ensure compliance with all non–transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. The module is limited to OEM installation ONLY. The module is limited to installation in mobile or fixed application. We hereby acknowledge our responsibility to provide guidance to the host manufacturer in the event that they require assistance for ensuring compliance with the Part 15 Subpart B requirements.

IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain laptop configurations or co–location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re– evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

23.2.3 End Product Labelling

This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labelled in a visible area with the following: “Contains FCC ID: 2AJMTWIPY01R”. The grantee’s FCC ID can be used only when all FCC compliance requirements are met. The following FCC part 15.19 statement has to also be available on the label: This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions: 1. this device may not cause harmful interference and 2. this device must accept any interference received, including interference that may cause undesired operation.

23.2.4 Manual Information to the End User

The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. In the user manual of the end product, the end user has to be informed that the equipment complies with FCC radio–frequency exposure guidelines set forth for an uncontrolled environment. The end user has to also be informed that any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate this equipment.
