Great project, would you be looking at selling any prototypes? I would be very interested in testing them out.

No need to pay, you can download the Gerbers and get 5 boards manufactured for under $10 shipped!
Choose JLCPCB, PCBWay or whatever similar service you prefer.

I do a lot of work on embedded pharmaceutical product security / pen testing etc and would be interested in looking at these.

Sounds good! Keep in mind this is a pure breakout board.
You will need to create the necessary connections & small components (resistors, capacitors, oscillator) and provide 0.4V power; then you should be able to interface it through serial.

From https://raw.githubusercontent.com/skot/bitaxe/master/bitaxe_schematic.pdf, we can see which values Bitcointalk user Skot used for his (dual chip) prototype and on which pins.
I guess he got the information at least in part from this Bitmain Antminer S9 repair guide: https://www.zeusbtc.com/manuals/repair-guide/Antminer-S9-hash-board-Repair-guide.pdf

Oh, he also uses 2x TCR2EF18 to get the 1.8V that are required on some pins.
Not sure about the power supply, though. I overspecced the connector to be able to push up to 32A, but his README says he suspects 3A to be enough.
It's not easy to get cheap lab PSUs that deliver 0.4A at over 10A, but 3A is no problem.

I will continue my experiments, soon!

Bought, will be a bit of fun. Thank you!

I once made a miner from my Python FPGA, il be honest, it was not great but it kept me busy for a few weeks
