Over at the Arduino forum, member Dan Combine has published details for his "Quadratron" - a four channel fully isolated power transistor control board for use with an Arduino Mega or compatible board. The purpose of this board is to provide a flexible, modular and isolated way to drive 4 power transistors, which can be configured in variable ways, e.g. H-bridge. This can be used to drive DC and AC motors, transformers, coils, single- and double-rail circuits, single-phase driven 3PH motors, and more. Furthermore the isolation is rated for voltages up to 1 kV and the logic control is fully isolated from the Arduino board.
And as Dan has published the Quadratron as open-source, you can download the design files and make one for yourself. For more information, discussion and the design files - login to the Arduino forum. And for more news and information, follow us on twitter and Google+ as well.
Need a matching Mega-compatible board for use with the Quadraton? And want to add Ethernet connectivity? Then check out our Freetronics EtherMega:
Quite simply the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
