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
