The Embedded Controller arrives from the UK

My ADM5120 Embedded Controller arrived from "across the pond" after what I assume was a short delay by customs. I purchased the board with all the options except I needed a US power supply. I went with a 12 volt 500 mA power supply, the EPS 120050-P5P made by CUI Inc and ordered from Digikey. Yes, you read correctly. It's only 6 watts! I'm dreaming of the lower power bills I'll see after I turn off the old PC that is my current server.

The board was up in 5 minutes after I unpacked it. It would have been 1 minute if the USB to TTL serial cable had been keyed.

This weekend, I'm building a Lexan base to mount the the board on. I've already learned a couple of methods to cut Lexan that don't work. The Dremel just melted the plastic. In the end, a slow moving jigsaw with a metal blade did the trick.

Embedded Linux Project

A few weeks ago, I started a small side project using the Freescale ColdFire board I mentioned in a previous post. The board was fun to work with but I quickly found that the lack of memory and a more capable operating system was really getting in my way. To solve this problem, I've moved on to an embedded Linux board with:
  • 2MB Flash / 16MB RAM
  • Provides Internet/Ethernet connectivity
  • Provides USB host connectivity for WiFi, Bluetooth, Audio and most USB to serial devices
  • Easily connects to I2C devices
The best part of the board is it's support for a large suite of software packages and plug in devices. Hopefully, this hardware upgrade will jump start my hobby project and let me write more application code and spend less time on extending the Board Support Package (BSP).
