1. Supports 24 channels of simultaneous measurement of ADC values, the input voltage is 0~3V, and each ADC port has added TVS protection. The measurement speed can be changed through AT commands, with a maximum upload speed of 10K times per second. Cooperate with Vofa+ host computer to display the voltage waveform in real time. 2. The main control chip uses STM32F407ZET6 as the main control chip. The measurement input voltage range is 0~3V and cannot be used with overvoltage. Multiple upload rates can be set, up to 10K times. Works with Vofa+ host computer to display voltage waveforms in real time. 3. Debugging interface, 24 channels of simultaneous measurement lead to the microcontroller debugging interface. You can develop your own firmware. Type-C interface for power supply and data transmission. The Type-C interface uploads the calculated voltage value and the serial port uploads the ADC value.
