This page describes the process of building and testing a board. Images & minivideo coming soon!


There are only 17 components so it's not very time consuming to make one of these
  1. Solder on FTDI chip. Its the most difficult part and its best if you have plenty of space to maneouver. Use a fine tip soldering iron and thin solder or solderpaste.
  2. Solder the surface mount resistors, capacitors, LEDs and inductor bead. Usually this is done by melting a small amount of solder onto one of the tabs, then tacking the part down and doing the other side.
  3. Solder the 6MHz oscillator and USB connector.
  4. Solder either a 4-pin SIP or cable to the power, ground, RX and TX lines. If using a cable, use a mini-ziptie to strain-relief the cable through the small hole in the corner. The pins are: RX (to computer), TX (from computer), GND and +5V (from computer) in that order.
  5. You can now plug in the board and test that its working. A computer should auto-detect the device, which will be called "USB<--->Serial" or something. Depending on your operating system, start up a terminal program for the right serial port, note that when you send characters to the port, one of the LEDs should flash. Don't forget to turn off hardware handshaking and flow control.
  6. Enjoy!
