ADC on Maix Go board


On the Maix Go board there are two pins labeled ADC near to where the LCD connects. However, the LCD uses I2C for its touch screen digitizer and the K210 seems not to have ADCs. Are these connected to anything? Maybe the STM32F103C8T6? If so, can they be read somehow?


it is connect to stm32, in the open-ec firmware, adc can be read by I2C.
