3.7 Visible light sensor
One phototransistor (Q1) is connected to ADC input channel SE3 of the K32L3A6 for evaluating the
ADC module as shown in
Figure 11

Figure 11. Visible Light Sensor circuit
The light sensor Output is shared with J4-6. The light sensor maybe isolated from the K32L3A6 device,
and J4-6, by cutting the shorting link SH1. The light sensor is powered by VDDA_K32L so if VREFH is
