Complete working unit 3
So this is al 3rd prototype fully functional with Teensy 4.1 developmentboard.
I usually do not sell finished detectors but need some funds, and do not need this one anymore.
This one has a prototype PCB with some SMD parts. I uses the Teensy 4.1 with the additional memory so one has a nice pre-recording buffer.
It has a jackplug for external microphone (internal switches off when external is placed) a GPS receiver and temperature sensor.
It does not come with charger (std micro USB) also no headphones and no micro SD (SDHC class 10, 32GB or less) memorycard.
