One of the World’s Smallest I2C Pressure Sensor Evaluation Board (0.4” x 0.29”) NPA 201-EV
Description
The NPA 201-EV is a small and easy-to-use I2C Pressure Sensor evaluation board measuring 0.4”x0.29” and has standard 0.1in/2.54mm headers for easy use with a bread-board and is small enough to put right into an application. It is based on the Nova Sensor NPA 201 which comes in a 2.0x2.5x1.0 HCLGA style pack- age. The NPA 201 can measure 260-1260 mBar absolute pressure range with 16bits of Resolution. Tem- perature measurement is also included. The NPA is operational from 3.14 to 3.46V and can operate across a -40°C to +85°C temperature range. The NPA 201 offers an ULTRA-LOW power SLEEP mode of ~20nA Typical and ACTIVE current is 35uA Typical. The NPA 201 utilizes a SIMPLE 3 Command I 2C interface(Command Request, Read Status, and Read Data). The NPA-201 is already calibrated, so there is no need for REGISTER INITIALIZATION needed. Upon Power Up the NPA 201 is ready to go as it is initialized internally. The NPA 201-EV is compatible with the Embedded Masters Rapid Prototyping Wireless Sensor Kit, EMSENSR-WSP (Wireless Sensor Plugin) and EMRF-WSB (Wireless Sensor Base). The EMSENSR-WSP provides a Sensor Plugin platform that all EMSENSR’s can be plugged into. The WSP can be directly con- nected to all of the Silicon Labs EFM32 Starter Kits on one side. The other side allows the EMSENSR- WSB to be connected to provide a BTLE connection using Broadcom based BTLE solutions. www.embeddedmasters.com Amphenol Advanced Sensors NPA 201 Full Datasheet link: http://www.amphenol-sensors.com/en/products/pressure-mems/mems-sensors/3236-npa-201 Gerber files and PCB Footprints are available upon request.
