Seeed 103030029 Raspberry Pi Relay Board for A+, B+ & 2

The Raspberry Pi Relay Board from Seeed Studio gives you 4 relays that will switch 15A at 30V DC/250V AC each, easily enough for most applications. The board uses the older 26-pin GPIO connector so it's compatible with every Pi from the old A to the new Zero. Screw terminals are provided for the connections to the device being switched and an LED indicator shows the status of each relay's normally open (NO) contacts. Your Pi can control the board via I2C and each board has a programmable address making it possible to drive multiple boards. PCBs with high voltages including mains electricity can be dangerous, please take precautions to prevent shocks and short circuits.

• 4 x relays with 1 x NO and 1 x NC contacts each
• 3-bit I2C address selection (8 addresses)
• LED indicators on each relay
• Screw terminals for switched devices
