@ Dennis,
You are still doing better than me...When it comes to this family of boards I'm in the "Everybody knows pie are round. Cornbread are square" camp.
A Pico as What kind of peripheral?
@ Casey,
Mounted inside the radio you can tap the single ended side of the com bus and tie the Pico to a BT radio mounted outside the case.
Outside the case, taking advantage of the differential bus noise immunity use the CH end of the cable. `
