Module 4Relay

SKU:M121

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.

Product 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)
