Atmega328 + 3-axial Accelerometer + XBee

October 8, 2011 2 comments

I’m adding this custom Atmel-based wireless sensing node equipped with an Atmega328, ADXL335 3-axial accelerometer and Digi’s XBee. The board can be flashed with an Arduino bootloader and programmed just like another Duemilanove or Pro. In terms of Arduino, this is a combined Arduino Pro, XBee shield and a third sensor board. The size of the board is a tiny 2.00″ x 2.15″. It’s DFM.

PCB Design Using Eagle CAD Software

October 2, 2011 1 comment

I am posting this one as an advertisement for my PCB design work. I have expertise in PCB design using Eagle CAD software. And I have some samples that I put up in this post. This is an interface circuit for the Arduino Mega 1280 for several applications. This is not a full custom PCB. Instead, this integrates several sensor and wireless communications modules for different applications.

It is made to fit the Arduino Mega as shown in the last photo.
