Another week has passed. I tested it twice this week. The first time, as everyone said, I couldn’t connect to the Internet. After trying N times, I still failed. Later, I found that I needed to use a ...
In micropython, there is currently no method to disable the ADC. Once the ADC is enabled, it cannot be turned off, so there is still more than 1 mA current in the sleep state, which is relatively high...
As shown in the figure, I converted +5V to -5V through MAX735, and then supplied the positive and negative 5V to the dual power amplifier. Once powered on, -5V was pulled down to 0V. After disconnecti...
