Review on 🔌 Huayao 2pcs 4 Channel 5V Relay Module with Optocoupler for Arduino UNO R3 MEGA 2560 1280 DSP ARM PIC AVR STM32 Raspberry Pi by Jacob Ashman
Good value for money. Works without problems.
Good for my needs. The two-pack ordered works perfectly when tested. The included case is a bit cumbersome to assemble.
- This relay module has a low active voltage of 5V. The maximum relay output contact is 250VAC 10A and 30VDC 10A.
