Review on π Latest Raspberry Pi 8-Channel Relay Expansion Board with 5V Power Relay Module for Raspberry Pi 4 3 2 Model B+ B Jetson Nano - XYSGStudy by James Daniels
Works well, good mounting solution
No documentation, but the GPIO to relay mapping is on the circuit board under the yellow jumpers. This is misleading as they are marked as P5, P6, P13, P16, P19, P20, P21, P26 but they are actually GPIO, GPIO5, GPIO6, GPIO13 etc numbers not PI pin numbers.
- This allows your Pi to drive high voltage products such as home appliances.
- Good, but not great
