@Tim 'mithro' Ansell Yes, Kassem told me to do that. My designs would not work with caravel pad rings because they are for high frequency (~2Ghz) and the caravel pad ring is supported for (I guess) 50 Mhz. I would really appreciate if I can get the bare die. I'll search for a facility that can wirebond the chip or even a place that allows me to do that. I've done quite a bit wirebonding and assembly work in my PhD.
Hopefully, there will be some circuits in mpw-one that are fully functional. 😇
