USB-to-Serial Adapters Revisited

摘要

Back in the June 2010 installment of the Primer, we discussed the FTDI USB-to-TTL serial cable, and how a single cable can be used to both power and program a PICAXE breadboard circuit. The FTDI cable is simple to use, plus it consumes much less breadboard space than the standard AXE027 programming cable and a separate power supply. As a result, I almost always choose the FTDI cable whenever I'm setting up a new PICAXE breadboard project.
