This is a low-cost digital-to-analog conversion module based on the PWM+ADC solution.
It has the following disadvantages:
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.
The minimum output voltage of channel 1 (O1) is 0.05V, and the minimum output voltage of channel 2 (O2) is 0.1V
3 There is a 10-20MS high pulse at the moment of power-on
