I just picked up a few extra Avalon miners but could not get a AUC3 to connect them to my PI. If any one is willing to part with a AUC3 please PM me.
Thanks
what Avalon is it 6 or 721/741 you can by pass the AUC with a cable on four pins on the GPI on the RPI

You can go here
https://www.parallelminer.com/product/avalonminer-raspberry-pi-controller-for-a6-modded-to-bypass-auc2/ an buy the molded RPI with cable by passing it.
if it's the 721/741 you would have to find out what pins to use on Avalon site an make your own able cables,they give that info.
other wise if it's A6 they use AUC2 the AUC3 is suppose to work on the Avalon 6,can't say for sure i don't have a A7 yet to find out .
Make sure you have the right image for the right miner and PI because the ACU2 won't work on the A7 aka 721/741 an the image will matter for miners because of the drivers and setting in the image even if the RPI boots . .
