Description

4-Relay Module is a 4-Channel Relay module compatible with M5Stack Core and Core2 series, with 4-channel mechanical relays (NO, COM). It supports I2C protocol. Also, it can be set by jumper into active/passive modes. This relay module supports DC control only, and Maximum load 24W (DC 24V@1A). Suitable for small load circuit control.

Features

• Embedded with STM32F030F4:
  • I2C communication (Addr: 0x26)
• Relay:
  • 4x relay module (COM, NO interface)
  • Maximum load 24W (DC 24V@1A)
• Supports two operation modes (selected by jumper).
  • Active mode.
    • Power input connects with relay NO port, to supply load directly.
  • Passive mode.
    • Power input not connects to the relay port. The user's circuit needs individual power supply.
• Power input (Support DC input only).
• DC 5-24V INPUT -> M5 BUS HPWR Bus (Controlled by jumper. When stacking with several different M5 modules, HPWR Bus can supply power to other modules that need 24V power, such as SERVO2 module, etc.)
• Development platform: Arduino, UIFlow(coming soon)
