The necessary connections between the PIC18F57Q43 Curiosity Nano board and the required click boards are shown in
Figure 7-1. The
full system setup is shown in Figure 7-5.
- The Click 1 expansion connects to the
Mic Click Board™. This uses the AN1 pin to transfer analog voice signal to the ADC
on-board the PIC18F57Q43. The Mic Click Board™ has a
signal conditioning and filtering circuit on board.
- The Click 2 expansion connects to the
Flash 2 Click Board™. This board has the SST26VF064B Flash memory module by
Microchip and uses SPI to communicate with the microcontroller.
- The Click 3 expansion connects to a
custom made Class D power amplifier circuit on a PROTO Click Board™.
