I have an Ardupilot V2.4.1 board. Inputs IN4/5/6 don't work and there is a defect on the top of the MEGA32U PPM chip that indicates its fried. Everything else seems to work. The top of the chip reads:

(ATMEL logo)

MEGA32u2

10268      TH

OF4378

I can't find an exact replacement chip. Does anyone know if one of there will work or where to get a suitable replacement? https://www.digikey.com/products/en?KeyWords=mega32u2&WT.z_head...

I'm planing on replacing with a hot air rework gun. I'm good with small fiddly things like this but have never redone an SMD component like this or used a rework gun. Let me know if you have tried and its not feasible.

I'm wondering if I would be better off getting a 2.6 or 2.8 board. I'm not wanting to dump a bunch more money into this now our I'd get something else.
