Module13.2 4In8Out is an 8-channel MOS driver output + 4-channel passive contact input IO expansion module. It uses STM32F030 as the I2C IO expansion chip, supports 9 ~ 24V power input, and has a built-in 5V DC-DC circuit.
Features
Compatible with Basic/Fire/Core2/CoreS3 and other hosts
Uses STM32F030 as the IO expansion chip, communicates with the host via I2C, and the I2C address can be modified by writing to the register
8-channel common positive MOS driver circuit (A3400), capable of directly driving loads, with a maximum switching current of 1A per channel
4-channel common ground passive contact input, cannot connect to active signals or signals greater than 5V
Default 0x45, can be modified by writing to register 0xF0
