[EOL] 4-Channel Relay Module (STM32)

This product is EOL. Please order the new version Module13.2 4Relay v1.1

Description

Module13.2 4Relay is a relay module compatible with M5Core/Core2 controllers, featuring 4 mechanical relay control channels (NO, COM). The module uses the I2C communication protocol, effectively saving IO resources. The jumper cap design allows switching between active/passive working modes to meet different circuit requirements. This relay module only supports DC circuit switching, with a maximum load capacity of 24W (DC 24V@1A) per channel, making it suitable for controlling small load circuits.

Features

• Embedded STM32F030F4 controller:
  • I2C communication interface (addr: 0x26)
• Relays:
  • 4 x relay control (COM, NO interface)
  • Maximum load capacity 24W (DC 24V@1A)
• Supports two working modes (controlled by jumper caps):
  • Active control:
    • Power input connected to the relay NO interface, directly powering the load.
  • Passive control:
    • Power input not connected to the relay interface; user circuit must include power.
• Power input (DC only):
  • DC 5-24V INPUT -> M5 BUS HPWR bus (controlled by jumper caps, when stacking multiple M5 modules, the HPWR bus can power other modules requiring 24V, such as the SERVO2 module)
• Development platforms:
  • UIFlow, Arduino

Includes

• 1 x 4Relay Module
• 5 x 2.54mm-2P terminal blocks (green)
• 10 x jumper caps
• 1 x wiring manual

Applications

• Solenoid valve control
