Description

Module13.2 4In8Out is an IO expansion module with 8-channel MOS driven outputs + 4-channel passive contact inputs. It uses an STM32F030 as the I2C IO expansion chip, supports 9 ~ 24V power input, and has a built-in 5V DC-DC conversion circuit.

Features

  • Suitable for Basic/Fire/Core2/CoreS3 hosts
  • Equipped with STM32F030 as IO expansion chip, communicates with host via I2C, I2C address can be modified by writing to registers
  • 8-channel common-positive MOS driving circuit (A3400), can directly drive loads, each channel supports up to 1A, total current not exceeding 8A
  • 4-channel common-ground passive contact inputs, cannot be connected to active signals or signals greater than 5V
  • Built-in MP1584 9 ~ 24V -> 5V DC-DC circuit

Includes

  • 1 x Module13.2 4In8Out
  • 13 x 2P Terminal

Applications

  • Multi-channel load driving (relay, air valve, unidirectional motor, signal indicator lights, etc.)
  • Limit switch, button detection

Function of the Onboard Toggle Switch
The red box in the figure below is the Boot0 control toggle switch. Switching to position 1 (high) enters firmware flashing mode. Switching to position 0 (low) reads user program from flash memory, i.e., normal operating mode.
