Plug and Play
Literally, plug it into your pi and you should pick up your gpio readings via the /boot/firmware/config.txtAlso turn on gpiopin=X and turn on, dtparam=i2c_arm=onIn my case it was one wire thermocouple so I'm looking at:/sys/bus/w1/devicesWorking with Raspberry Pi4

AhA!
This board here let me sneak into the world of one-wire hackery. A few jumper wires - a few little resistors n a breadboard later: n I was cloning what the manufacturer of a certain dental machine manufacturer thought they could charge $8,000 for. That's right. They used the obscurity of one-wire eproms to store a license key onto the firmware to lock out upgrade features. That's abuse of capitalism, using our technology against us. YA GOTTA GET UP ALOT EARLIER BUB!

Not enough drive current to flip a relay
I got this card to interface to a relay with a 5v coil. Sadly the output of this card is not enough control the relay.
