I don't think you'll find one that's an exact match. I think Jim Sheldon, W0EB, made some kind of PCB that allowed a Teensy to plug into a Nano socket, but I'm not sure. Jack, W8TEE

Thanks Jack, ? ? I suppose I should have been more specific - a more powerful board that would fit in the same form factor and at least more or less plug in.? Although amazing things can be done with little green jumper wires :). ? ? I actually have a couple of ESP32 WROOM cards right here on the desk. ?
