- solder jumper for slow programming
- switch to power devices with 5V if needed
- edge connector for pogo pins or socket
- the rest is basically a copy of the standard USBASP devices
I'm on vacation, not bored
Overall I'm pretty happy with it, but I'm a bit sad that I can't use this with boards where pinheaders are already present. Would have been nice to have a standard 2x3 ISP socket on it and change between cables, pogopins and avr clamps. When it comes to power, a little regulator for 3V3 would be nice too. Basically switch between 5V, 3V3 and selfpowered.
