Description
The breakout circuit board is equipped with a Bosch Sensor ME280 temperature, humidity & pressure sensor.
Board has selectable I2C address jumper (solder link GS2), I2C pull-up resistor, 7-pin header 2.54 mm, and two mounting holes 3.5 mm.
The default board setting. Single Power Rail VDD = VDD_IO (Solder Link GS1), Both Power Terminals Vdd and & VDD_IO Pull Up Resistance (R2, R3) 10K, Protocol Selector Resistance 0ohm (R1), Decoupling Capacitor 0.1μF
The board connects to both power sources to ensure that the GS1 jumper power rail is deleted for VDD_IO 1.8V and VDD 3.3V rails!
