a "true" in system programmer

I'm on vacation, not bored

Similar projects worth following
I want an AVR ISP programmer that uses the systems power on vcc and the gpio. It should use proper levelshifters (4 of them - SN74LVC1T45) giving a range of 1,65 <=> 5,5 on system side and whatever brain I choose for my progger. Can be especially interesting for boards with "exotic" chips and power levels.

  • 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

Order from OSH Park
