This is a YL-40 module with a PCF8591 ADC converter on it. I used a Raspberry Pi 4 to communicate with the module over I2C bus.Using included “suitcase jumpers”, on-board sensors can be connected to ADC inputs.Jumper P4 connects thermistor to AIN1.Jumper P5 connects light sensor to AIN0.Jumper P6 connects potentiometer to AIN3.Due to PCB error (no electrical contact or trace found), you need to solder a wire from other side of thermistor R6 to GND if you want to use the thermistor. (Both of my boards have this issue and others have reported problem online). If you just want to use the ADC/DAC, the 4 analog inputs and 1 analog output work fine. The potentiometer and light sensor work fine.
