STM32 10-channel ADC module uses the internal 10-channel ADC resources of ST's STM32F103 family of microcontrollers as the sampling core. Having better accuracy and the ADC data can be uploaded to PC.
1, Onboard STM32F103C8T6 master chip;
2, Onboard CH340 serial port to USB port chip, it is convenient to see AD sampling results on your PC;
3, Reserved UART serial communication interface, can be connected to extern MCU;
4, Analog input channels: 10-channel single-ended inputs;
5, Sampling voltage input range: 0-3.3V;
6, Power supply voltage: 5V / 3.3V
7, Resolution: 12 Bit (4096);
8, Infos: https://pan.baidu.com/s/1dFw3tYD
Testing example: when IN0-IN4 connect to 0V and IN5-IN9 connect to 3.3V, we can see as below:
On Linux run the following command miniterm.py /dev/ttyUSB0 115200
1 x STM32 UART Communication ADC Module.
