This is a USB to UART board that allows easy reprogramming of the LilyPad main board without the need for soldering. This board is based on the FT232RL IC from FTDI.


  • Implements full v2.0 USB protocol
  • Needs no external crystal
  • Internal EEPROM for device ID and Product Description strings
  • Royalty-Free Driver support for Windows, Linux, and Mac OS X

This is great for programming the LilyPad, as it requires no soldering or alterations to the Arduino Mini programmer (and has a flatter form factor), and it slots right onto the board! – Link.
