#Coral Environmental Sensor Board
|
|
|
|
The Coral Environmental Sensor Board adds multiple environmental sensors and Grove connectors for external devices. It works with all 40-pin Rasperry Pi variants as well as the Coral Dev Board.
|
|
|
|
Features:
|
|
|
|
* 128x32 OLED Display (SSD1306-based SPI interface)
|
|
* Ambient light sensor (OPT3002, 0x45 on i2c bus)
|
|
* Barometric pressure sensor (BMP280, 0x76 on i2c bus)
|
|
* Humidity / temperature sensor (HDC2010, 0x40 on i2c bus)
|
|
* Cryptoprocessor with Google keys (ECC608, 0x30 on i2c bus)
|
|
* Four Grove connectors:
|
|
1x UART
|
|
1x I2C
|
|
1x PWM
|
|
1x 3.3/5V analog (using TLA2022 ADC, 0x49 on i2c bus)
|
|
* General purpose button
|
|
* General purpose LED
