Instruction manual Please ask us after the purchase
 
Note:
This is a low-cost digital-to-analog conversion module based on the PWM+ADC solution. It has the following disadvantages:
1 channel 1 (O1) has 1% accuracy at 1-5V, <1V has 50HZ/40MV ripple, channel 2 (O2) has 1% accuracy at 2-10V, and <2V has 50HZ/80MV Ripple.
2 channel 1 (O1) minimum output voltage is 0.05V, channel 2 (O2) minimum output voltage is 0.1V
3 There is a 10-20MS high pulse at the moment of power-on
