Would it be possible (or perhaps permissible) to incorporate your design into my board? I'm planning on designing a cape which will do the following: 1 - Take an input voltage and use a step-down converter to produce 5V for the beaglebone 2 - Have a switch to toggle between wall power and battery power, and also a monitor to disconnect the battery if the battery voltage drops too low. 3 - Have the circuitry to talk on the bioloid bus (a single-ended half-duplex multi-drop megbit serial communication channel). 4 - Have an on-board I/O processor which sits on the bioloid bus. So I'm basically combining my brothers power board: http://www.huvrobotics.com/shop/index.php?_a=viewProd&productId=7 USB bus interface: http://www.huvrobotics.com/shop/index.php?_a=viewProd&productId=5 (except I'm going to go directly to one of the beaglebone UARTs) And a general I/O board: http://www.huvrobotics.com/shop/index.php?_a=viewProd&productId=6 except it will be all surface mount components. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
