@romiller49 posted:OK, since we are all learning something here, is there any way to check an R2LC or R4LC board without attaching it to the mother board?
Not easily. You can "skywire" it, but for a full test you really need to exercise stuff like the PWM and serial data.
I made a test fixture to test all the modular boards, TMCC and early Legacy. I use it a lot. For folks without such a tool or similar, do what I used to do. Poke the suspect board into a TMCC engine and program it and see if it works.

It's a PIC16F648A, In stock at Mouser. Also, Microchip Direct has them as well.
The R2LC-04 I looked at has the PIC16F84-04, it was obviously a fairly old one. That one is also in stock at Mouser.
