Gadgetboard: A Free Hardware Design

Posted 4 Mar 2007 at 00:01 UTC by steve Share This

A recent Open Collector annoucement describes the latest release of the Gadgetboard, "The Gadgetboard is a user friendly Atmel proto board on steroids. The ATMEGA32 comes programmed with a command-line interface which runs over the serial port, allowing the user to read the 8 analog inputs and set the 8 outputs. Four of the high current MOSFET outputs optionally drive 15-amp relays, while the other 4 MOSFETS are driven by the Atmel's 4 onboard PWM channels. All inputs and outputs are ESD-protected, and are connected to screw terminals." Best of all, of course, is that Gadgetboard is free (as in speech) hardware. The schematics and firmware are available for you to examine, modify, or reuse in other hardware designs under the terms of the GNU GPL. You can download the design and roll your own board, or you can buy a bare board, a complete kit, or a fully assembled and tested board.
