Arduino and the LTC2440 24bit ADC

Have you ever wondered how to improve the resolution of analog readings of your Arduino board? If yes, this is for you.

John Beale, discussing on the Dangerous Prototypes’ forum, quickly describes how to connect a Linear’s LTC2440 ADC to an Arduino board, which will provide you with an amazing 24 bit resolution.

The ADC, which is available in a SSOP package, can be connected to the Arduino via the SPI bus. Here John provides a brief sketch and some very useful comments to make it working properly.

Insert Coin: BoardX is an open-source, modular motherboard for prolific prototypers

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.
We're more than a little enamored with Arduino and its DIY microcontroller ilk. But we'll admit, there are a few limitations that the compulsive prototyper might find bothersome. Chief amongst them is the lack of modularity, Now, sure, you can easily add all sorts of sensors, ports and radios to your Uno (or Duemilanove if you're old school) but that generally requires piling shield, upon shield, upon shield, until you've got a stack of boards three-feet high. And, if you want to use an ARM chip instead of an AVR for a project? Well that's a whole other set of boards. Kevin Greene has decided to address these perceived "weaknesses" with BoardX -- a modular, open-source prototyping platform.
