Chintoo FM

This little FM buddy is based on the Philips TEA5767 FM radio chipset, Adafruit ItsyBitsy 32u4, PAM8302 audio amp, and a 4 digit seven segment display. The list of preprogrammed FM radio stations can be toggled by tapping on a tiny brass disc. I used Paul Stoffregen’s capacitive touch library here. The volume is controlled with a linear potentiometer in the back. Power comes over USB.
