No isolation resistors!

A project log for Revive "Wiring" ?

Low cost ATmega128A-based arduino-compatible PCB with original "Wiring" form factor.

Hmm.  Noticed (after ordering the PCBs, of course) that the circuit does not include the 1k "isolation" resistors  in the Serial RX/TX lines to the USB converter, that have become relatively standardin arduino-like boards...
