The enclosure is from Adafruit – about perfect, although it’s a pretty tight fit. The display is an OLED character display. (It’s a little quirky, and it draws more power than a regular LCD, but it’s really bright and clear.) The EM-406A GPS mounts on the top of the case. I drilled a small hole that shows the LED on the GPS module which lets me know when I have a fix. The IR detector is also on the top, so I can use a TV remote to set the parameters. The bottom has the on/off switch, (and now a piezo switch) and a slot that allows removal of the microSD card.
