Module13.2 4In8Out

SKU:M122

Description

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
Built-in MP1584 9~24V -> 5V DC-DC circuit

Includes

1 x Module13.2 4In8Out
13 x 2P terminals

Applications

Multi-channel load driving (relays, solenoid valves, unidirectional motors, signal indicators, etc.)
Limit switch, button detection

Function of the onboard toggle switch

The red box in the image below shows the boot0 control toggle switch. Toggling to the 1 side pulls it high for firmware flashing mode. Toggling to the 0 side pulls it low for reading user programs from flash memory, i.e., normal operation mode.
