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 wavecompatible withm 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 wavecompatible withms 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 compatible with power supply and data transmission. The Type-C interface uploads the calculated voltage value and the serial port uploads the ADC value. Onboard red power light, blue running Indicator light, reset button 4.
