Components and Assembly The extendable Arduino GPS data logger consists of a shield that is fitted with the GPS receiver, SD card reader, and accelerometer, together with an Arduino UNO board.

There’s also an SD card thrown in for good measure, making this one of the best tracking and data logging shields for the Arduino.

Now that tinkering has finally come to fruition with [Phang]’s TraLog shield, a single Arduino shield that combines GPS tracking with a GSM and GPRS transceiver. There’s also an SD card thrown ...

The GSM Shield also includes a Telefonica SIM card that includes a worldwide data tariff which can be used anywhere there is a cellular signal.

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

OMC's H19 fiber-optic shield has been adapted as a stackable add-on for the Arduino Uno. It’s designed to simplify the integration of fiber-optic data links into microprocessor-based platforms.
