USB Micro ISP v1.4

2 layer board of 1.50 x 0.80 inches (38.1 x 20.3 mm).
Shared on February 25th, 2015 21:22

A voltage-agile SMD AVR programmer. QFN/SSOP variant.

This version adds a recovery clock pin. With a slight mod to the firmware, the recovery clock pin will have a 500 kHz square wave during programming.

BOM:

  • R1 10K
  • R2 & R3 150R
  • R4, R5 & R6 1.5K
  • C2 & C5 0.1µF
  • C3 & C4 22pF
  • C6 1µF
  • C7 2.2µF
  • D1 & D2 1N4148
  • Y1 12 MHz
  • IC1 ATTiny2313
  • IC2 74HC365
  • IC3 3.3 volt LDO
  • IC4 AP2331
  • PROG Red 0805 LED
  • CONN Green 0805 LED
  • JP4 Micro USB-B
  • F1 500 mA PTC
