Other key parts include the BME280. By type, the board carries 3 capacitors, 2 connectors, 2 switches, 2 test points, 2 resistors and 1 IC.
It belongs with the sensors designs in this gallery.
From the project
PMOD module for the Bosch BME280 Temperature Humidity Pressure Sensor, connection over I2C.
This PMOD connects the Bosch BME280 humidity, pressure and temperature sensor over I2C, using Digilent's PMOD interface type 6A per PMOD specification v1.3.1. The PMOD module can be chained to add additional I2C devices to the bus. The I2C pull-up resistors can be enabled/disabled using DIP switches, and switch 2 toggles the sensors I2C address between 0x76 and 0x77.
