I ordered 10 more of these Digispark boards, I am down to my last two. I managed to brick one yesterday flashing a new bootloader. Default has a 5 second pause on boot in case the micronucleus programmer needs to flash a new sketch. Seems the binary I found isn't the stable version. Windows doesn't see the hardware now. What a waste of €0.89!!!
Keep up the good work, phenominal amount of info onmthe forum. I have parts ordered for a home made 1/4 wave ground plane antenna. How did testing go? Any other hints?
