Review on 🔧 Comimark 5Pcs Digispark ATTINY85 Micro USB Development Board for Arduino: Enhancing SEO by Tom Motko

This is not a Digispark but a fake. It doesn't work like the Digispark as sold. Should be 1 star but add another star because they are $2 each and all the parts are there but you probably didn't expect to blink. So they have a micronucleus loader, but they don't have one. work hard. By default they take the program from the Arduino IDE, but as soon as they lose power they revert to their default settings (fast blinking LED). micronucleus. Wire pins: Rpi-> this board as: GPIO17 -> P5GPIO18 -> P2GPIO23 -> P0GPIO24 -> P1GND -> GND5V -> VinI did this with tiny alligator clip test leads. Set up avrdude.conf:programmer id = "linuxgpio"; desc = "Use the Linux sysfs interface to bitbang GPIO lines"; type="linuxgpio"; reset = 17; sc = 18; Moses = 23; miso=24;;flash:command line: avrdude -p attiny85 -C avrdude.conf -c linuxgpio -v -U flash:w:t85_default.hex After this and loaded board profile everything works fine. Can be programmed with Arduino IDE and programs remain after power off. It's easier to handle this on a Linux machine - lots of driver issues on Windows. The seller advised me to google Attiny85 when I asked about the bootloader's strange behavior, thanks to Xie for the tip.
