2.3 SW3 navigation switch
The SW1 navigation switch connects to the microcontroller’s key interrupt input. The switch operates in
five directions and has a push function in the center.
2.4 J1: external A/D measurement inputs
You can configure connector J1 to measure external analog signals using the internal 10-bit A/D
converter or the MCU’s 16-bit sigma-delta A/D converter by opening the corresponding A1–A8 soldering
bridges.
