That board I sent out to fab?
I included the Arduino-style programming header... but omitted the AVR programming header for installing the bootloader. That used to be on my MCU-based-board checklist! I must be getting rusty, and also the checklist is around-here-somewhere instead of in front of me.
Oh, well... only half a dozen of this iteration; I can use one of the existing headers plus a tacked-on pin on the RESET- line, and a kludge cable. Assuming the system works as intended, I'll be making another run of the boards, with refinements.
Or, I could see about procuring a half-dozen chips with the bootloader pre-programmed. Might be easier. (Hm. Adafruit has them, but only in DIP format. Here's somebody with the TQFP; maybe... oh, ships from Turkey. Probably takes quite a while to get here. Kludge-O-Matic, here I come!)
