Designed for DEF CON 24 to compliment the Bender Badge by AND!XOR. The Cigar Mic adds an audio input to the Bender Badge in order to show a real-time spectrum anaysis of any activity occuring between 0 and 10kHz around the badge.
Cigar mic requires 3.3V, GND, an ADC input pin, and three 3.3V output pins. The included software is compatible with AND!XOR’s Bender Badge and should be connected as follows:
OUT -> PA1 GND -> GND 3.3V -> 3.3V L1 -> PA3 L2 -> PA4 L3 -> PA5
