Review on π GeeekPi Raspberry Pi Expansion Board 4 Channel Relay Board - Power Relay for Raspberry Pi 4B, 3B+, 3/2B (No Programming/Programmable) by Jeremy Gaines
new Pi? Computer components
First. This product is made by 52pi if you are looking for wiki pages not listed anywhere on this amazon page. that all NC terminals are shorted to ground and do not switch from NO to NC. So I connected 24V DC to NO and when the unit turned on I had no light but the NO side was hot. So I used the i2cset command to turn off this relay and here is the magic blue smoke. not even sure how that's possible, but oh well. As far as I know, this seller owes me another pi3b+ and a refund for this part.
- Like everything before
- Infinitely slow
