The LRADC channel of the processor that the Wiren Board uses to operate the ADC has an integrated current source. This allows to measure the resistance of the load connected to the outputs of the ADC, i.e., to read values of resistive sensors. | The LRADC channel of the processor that the Wiren Board uses to operate the ADC has an integrated current source.
