SALock Serial Adapter
This doesn't really belong in the Projects category, but I don't know where else to put it.
|+3.3||C99, side closest to R59|
|GND||C99, side closest to center of board|
|TXD (TTL -> RS-232)||Pin 13 on MAX3224|
|RXD (RS-232 -> TTL)||Pin 15 on MAX3224|
|CTS (RS-232 -> TTL)||Pin 10 on MAX3224|
Pins 19 & 20 need to be shorted together on the MAX3224 (datasheet) to disable auto-shutoff. After soldering 30 gauge wire-wrap wire to the pins, a dab of epoxy on each wire will keep them from breaking.
