1. Onboard TLC5615 chip, TLC5615 is a digital-to-analog converter with serial interface, its output is voltage type, the maximum output voltage is twice the reference voltage value, with power-on reset function, performance is better than the earlier current type output DAC is better, only need 3 serial buses to complete 10-bit data serial input, easy to interface with industry standard microprocessor or microcontroller (microcontroller)

2. The onboard TL431 voltage reference chip can also be connected externallyBenchmarkVoltage

3. All the pins of the chip have been led out and can be controlled and operated by the single-chip microcomputer

4. Working voltage: 5V
