Hi all,
This is my first time posting to this forum so go easy on me.
I have a ATMega328(non-p) that I accidentally bricked by selecting the Reset Pin as IO fuse bit.
This is on a custom PCB and the chip is very small(5mm x 5mm).
I was looking around at HVSP's but all of the one's I've found use an input socket for the repair.
Does anyone have recommendations for me here to get this unbricked?
Two options come to mind: replace the MCU using a hot air solder tool, or temporarily wire a suitable header to the PCB so that you can connect a HV programmer.
Hello @jremington, thanks for responding.
I may venture down the path of replacing the MCU.
How difficult do you think it would be creating a suitable header?
I'm not very skilled at precise soldering.
It should not be difficult to solder wires to the PCB traces, and lead them out to a free floating header. I use 30 gauge tinned wire-wrap wire for temporary fixes like that.
The header below was intended to inject signals mimicking those generated by the MCU that previously occupied that slot.
Right, thanks for that suggestion.
I appreciate the help! @jremington
