Bare PCB AVR Atmega, AtTiny fuse bit doctor HVPP HVSP fix restore factory repair

Description

Firmware, HEX files only (sorry I have no sources) and more information are in Description for this
VIDEO
You receive:
bare PCB for fusebit doctor, no components, BLACK solder mask HIGH QUALITY ENIG
GOLD
PCB !!!!!
Remixed original PCB:
Improvements:
+DC
barrel
for power supply
+Reorganized components
+
Integrated HVSP adapter
for Attiny84 and Attiny85
(you need just insert jumper to HVSP pins)
+
Integrated TQFP32 smd socket
for atmega328
(put MCU and hard press)
+No need remove pins form DIP40 socket
You can use adapters as in original version
You need only few passive components,  MCU with firmware (supported: atmega8,88,168,328) and sockets.

Leds explanation:
green(blue) on
– fusebits repaired. If lockbits are enabled, just verify fusebits with factory ones – and if they ok – light up green.
red on
– signature problem, can’t read, no device in socket, or no such signature in database.
green(blue)flashing
– signature ok, fusebits are wrong. Lockbits enabled, chip erase permission required (read below).
red flashing
– signature ok, no lockbits, but for some reason can’t write new fusebits.
