TK discusses a portable power supply module known as a Battery Shield for Raspberry Pi and Arduino.

The power supplies have overvoltage and overcurrent protection and an LED indicator. For ease of installation, each model can be mounted on a standard DIN rail. L-com’s new open-source Arduino PLCs ...

Yes, there is a chance to realize one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the little circuit ...

Freescale's Freedom Development Platform for the Cortex-M0+ Kinetis family supports Arduino shields. These boards provides access to a wide range of peripherals.

The power supply is a switching design with some filtering on the motherboard. One of the boards of the power supply module rectifies the incoming line voltage to a high DC voltage (about 400 volts).
