Complete working unit (Teensy 4.1)
Yes, this one is finished.
I usually do not sell finished detectors so this could be your chance to get one without building it yourself.
I buit this one for recording a video of the build. There are two PSRAM chips installed but it has no other options on board. (ext. mic. connector, GPS and temp. sensor)
It is fully functional, with built in li-po battery of approx. 8Ah. Ready to go.
It does not come with charger (standard micro USB) also no headphones and no micro SD memorycard. (SDHC class 10, 32GB or less or larger can be used formatted to FAT32)
