I don’t have the schematic but I checked it with my multimeter and it has the same connections with blinkstick.
The only differences are the values of the resistors. The resistor between ATTiny pin2 and D- is 220 Ohms. The same for the resistor between pin 3 and D+. The resistor between 5V and D- is 1K.
There are also 2 leds with resistors and a 78l05 voltage regulator but I don’t think they are relevant.
I think this board is a Digispark clone. As I have read, depending on the fuses settings, the reset pin might or might not be disabled. If it was disabled would I be able to upload the blinkstick firmware?
