WebApr 13, 2024 · The CSB (Chip Select Bus) pin determines which bus to use. A logic HIGH selects the I2C bus. A 10K pull-up resistor on the module pulls this pin HIGH and so the I2C bus is selected by default unless this pin is grounded. The module supports two different I2C addresses, either 0x76 or 0x77 which allows up to 2 sensors to be used on the same … WebDec 9, 2024 · Using Arduino Microcontrollers. pistonsoup August 10, 2024, 2:40pm #1.
