Module 13.2 4IN8OUT
SKU:M122
Description
MODULE 13.2 4IN8OUT is a '4-Channel Passive Input/Switch + 8-Channel MOS Drive Output' drive module. Adopt STM32F030 as the I2C IO chip, support 9-24V DC input, with internal DC-DC circuitry to 5V.
Product Features
- Compatible with Basic/Fire/Core2/CoreS3
- Adopt STM32F030 as the IO chip, I2C communication, I2C address is changeable by modifying the register
- 8-channel MOS Drive circuitry share the same VCC, channle load <1A
- 4-channel Passive Input share the same GND, no active signal or >5V signal allowed
- With internal MP1584, 9~24V -> 5V DC-DC converter
Include
- 1x MODULE 13.2 4IN8OUT
- 13x 2P Terminal
Application
- Multi-channel load drive (Relay, Valva, Single-phase Motor, Singal LED)
- Limit Switch or Button test

Schematic
Function of on-board toggle switch
In the red box below is the control toggle switch of boot0. Turn it to end 1 and pull it up to be the firmware scrub mode. Dial to 0 end pull down is to read the user program from the flash memory, that is, normal usage mode
