USB Interface 10 Channel 12Bit AD Sampling Data Acquisition STM32 UART Communication ADC Module

STM3210 ADC module uses the internal 10 ADC resources of ST company STM32F103 series as the sampling core, and transfers the acquired sampling data to the memory through the internal DMA of STM32, which reduces the CPU load and enhances AD. Sampling stability and accuracy, while the onboard USB to serial port chip can transfer data to the host computer. Features: 1. Onboard STM32F103C8T6 main control chip. 2. On board CH340 serial port to USB chip, convenient to view AD sampling results on the PC through the USB port. 3. Reserve UART serial communication interface, which can be connected to MCU. 4. Fine workmanship makes sure good performance. 5. 100percent brand new and high quality. Specification: Analog input channel: 10 channel single ended input Sampling voltage input range: 0 3.3V Power supply voltage: 5V 3.3V Resolution: 12 Bit(4096) PCB Size: about 5.1*3.5cm 2*1.38inch Package List: 1 * Module Note: 1. The sampling voltage input terminal INO IN9 can be connected or only partially connected. When a certain channel has no sampling voltage input, the output of the channel is a random value. The unused port can also modify the program as a normal I O port use. 2. The use of voltage can not exceed 3.3V, otherwise there is the possibility of damage to the chip.
