As an alternative to wiring up a voltage converter chip, you can instead go directly to USB with a USB-to-serial chip such as a PL2303. The "traditional" arrangement is: USB-to-serial dongle -> DB9 -> serial cable -> DB9 -> 12V-to-3.3V-voltage-translator But inside the USB-to-serial dongle

Re: Laptop debug

No. You can use a standard USB/RS-232 serial converter, but you will also need a voltage translator (such as a Maxim MAX3233 --- you used to be able to get free samples from Maxim) and a male and female connector to connect to the board. I'll dig up the connector spec (Digikey carries them) and
