Please check out the Hickory RET6N at <a href="http://www.spoatech.com" rel="nofollow">http://www.spoatech.com</a>. It is the first of several versions coming. Full documentation and more pictures will be posted as time permits. I would appreciate feedback/comments/ or "gee, it would be nice to have ???" inquiries as well. This board will also be offered without the RET6 processor as a shield to plug onto a Maple. </p> http://forums.leaflabs.com/topic.php?id=3435#post-14242 Sat, 15 Sep 2012 11:57:11 +0000 wdsim 14242@http://forums.leaflabs.com/ <p>Sorry, not yet ... working on that. Hopefully have one up in a couple of days. </p> http://forums.leaflabs.com/topic.php?id=3435#post-14237 Sat, 15 Sep 2012 11:01:20 +0000 mconners 14237@http://forums.leaflabs.com/ <p>Is there a URL to check it out? </p> http://forums.leaflabs.com/topic.php?id=3435#post-14236 Sat, 15 Sep 2012 10:48:54 +0000 wdsim 14236@http://forums.leaflabs.com/ <p>Based on the Maple RET6, the Hickory has many of the peripherals onboard that shields would otherwise offer. In addition to the Maple/Arduino standard connectors that still allow a shield board to be attached, the Hickory has onboard:</p> <p> * RTC from Maxim, the DS3234SN<br /> * 8Kx8 serial EEPROM, the 25LC640A<br /> * Ethernet port, by way of the WIZ820io<br /> * 16 channels of Op-Amp buffered analog input that can be configured as bridge amplifier inputs or simply as non-inverting op-amp buffers with gain<br /> * 8 channels of PWM output each rated to 40 amps, using N-Channel MOSFETS rated at 30 Volts<br /> * The Hickory measures 2.125 inches wide by 4 inches long<br /> * Single voltage supply input between 12 and 24 volts - rated at the current needed by the PWM loads<br /> * Onboard regulators provide supply regulation for the analog circuits and STM32F103RET6<br /> * MOSFET circuits are supplied directly from input voltage.<br /> * Uses RET6 bootloader and programs through USB port just like the RET6</p> <p>I plan to offer this board for sale through web sites like Sparkfun, but if anyone is interested in a board now, I can get one to you! </p>
