For uploading to “home made Arduinos” or other boards not equipped with an USB/TTL-serial converter chip like the Boarduino, there’s a few adapters out there. One of which is the standard FTDI USB/TTL-serial cable, which costs 20$ in the USA and more than 20€ in Europe (that’s the usual rip-off, as 20$ ~ 14€). Sparkfun also has FTDI breakout boards, but they are not as attractive as the next one. A much more appealing device is the ‘BUB’ board by ModernDevice. It’s much cheaper (13.50$ including a mini USB cable) and has more options.
- jumper for 3.3V/5V logic level selection
- breaks out more serial signal lines (DTR …)
- supports auto-reset for Arduino boards out of the box
- remappable header
- 3.3V power line selectable (50mA)
- LED for RX/TX activity
There’s not much to say other than that I like it! Assembly is quick and easy, the rest is plug and play. It fits perfectly to my RGB LED Matrix controller ;-)
Here’s the BUB manual.
