pippyg remote microphone version UPDATED 5TH SEPTEMBER NOT YET TESTED
AS ALWAYS - THIS IS SELF-BUILD PROJECT, THERE ARE EXISTING COMMERCIAL PARTNERSHIPS IN PLACE FOR ASSEMBLY AND MANUFACTURE.
DO NOT ATTEMPT TO ORDER PCB ASSEMBLY, ORDERS WILL BE CANCELLED.
NOTE - THIS *EXACT* REVISION HAS NOT YET BEEN TESTED - A SIMILAR VERSION IS KNOWN TO WORK, BUT ORDER AT YOUR OWN RISK.
This version removes the reflash button and replaces it with a pair of exposed contacts that must be shorted together to reflash.
The snap-off region is a remote microphone circuit, and also contains all the active analog circuitry. A 3.5mm headphone jack connects 3.3v and GND between the 2 PCBs, and brings the amplified signal (0.0 to 3.2V) down to the Pico for digitisation.
