Mixed-signal SOC
China's first low-power sensor measurement solution
  • High precision

    Two measurement channels.

    Measuring accuracy of 50,000 to 1.

  • High system integration

    RISC MCU + High precision ADC + BLE4.1.

    Integrated LED/LCD driver.

  • Rich system resources

    No external crystal oscillator required

    for 9600 baudrate UART.
