 That's amazing. The Pi stuff is incredible.
 We're designing around the RP2040 chip now. Dual-core ARM for 70
cents. It's rated at 133 MHz max, but overclocks to about 400. Some
lunatic froze one and ran the core voltage up and got it to work at 1
GHz.
 We're now designing an interposer board, to connect to a Pi 400 on one
end and to a 20-pin ribbon cable, to our DUTs, on the other, for
development and for production test both. I can post the schematic if
anyone is interested.
