Nope, they are just single resistors in a "pack of 4".
Okay, good to know. Thank you.

Okay, 3 years later and I have finally got back to looking at why this H5 A3 board was not booting. Turns out the fix on the reset IC22 was soldered to the GND pin 1 and not pin 2 :oops:

The board is now booting and shows a desktop so another one comes to life. :)

Here is the correct location of the IC22 bodge wire:

I guess this means that my other three A3 boards should now be built up.

Having gotten the first H5 A3 board booting, I now have board 2 alive and booting.

On board 2, I added all the fixes bodge wires on the top leaving the bottom side clear of wires. :D

Board 3 and 4 will also be brought to life.
