Hello,
i’m new to the Heltec dev-boards and i have a question regarding a BMP280 Sensor. This Sensor has VCC, GND, SCL, SDA, CSB and a SD0 Pin.
How do i connect this sensor to the HTCC-AB01 dev-board?
Best Regards,
Martin
HTCC-AB01 and BMP280
just connect:
VCC - VEXT
GND - GND
SCL - SCL
SDA - SDA
When you use IIC, you only need to connect
VCC-VEXT/VDD
GND-GND
SCL-SCL
SDA-SDA
When you use SPI, connect like this
VCC-VEXT/VDD
GND-GND
CSB-CS
SCL-SCK
SDO-MISO
SDA-MOSI
