GPY overview
GPY is a component documented by Pycom. The PDF description identifies it as "the latest Pycom triple–bearer MicroPython enabled micro controller on the market today – the perfect enterprise grade IoT platform for your connected Things. Version 1.0." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.
Datasheet snapshot

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- No pullup/pulldown internal resistance Absolute MAX per pin 12mA recommended 6mA!
- 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.
- To access this mode, you need to connect P12 to 3.3V and reset the device.
- Depending on the duration the pin is held at 3.3V, a different firmware will be run.
- 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.
- 448KB eFuse 256 bits are used for the system (MAC address and chip configuration) and the remaining 768 bits are reserved for customer applications, including Flash– Encryption and Chip–ID 1kbit – 802.11 b/g/n/e/i – 802.11 n (2.4 GHz), up.
Engineering review checklist
- Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
- Check package pinout, boot configuration, programming interface and silicon-revision errata.
- Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
