agree. RESET is not broken out. I cut a trace and soldered a flywire onto the exposed pad, that works fine, but sheesh what a pain.

Looks like the original source of the error is us; fixed.

Yep - 128KB program flash, 20KB program RAM. Although, the bootloader reserves an unnecessarily large chunk - 20KB - of the program flash, so you really only get 100KB. You can bypass this using the serial bootloader if you really need the extra space.
Glad to hear it! The RET6 has been a very successful beta and a near future revision of Maple will be armed with the same RET6 chip! I wanted to point out to you that while 17us is awesome, you can go WAY faster with some clever code-massage and analog care. For low impedance signals you can sample at 500ns! Seriously.

We plan to fix this in a future edition, but right now the problem stems from a conflict with the battery charger and the auto-power-sel scheme.
We made two changes on rev5 to fix the 1/10" issue. We added a second row of pins along the top header that are identical to whats on the arduino-positioned first row, but are on the 1/10" grid. We also shifted the right side header to sit on the 1/10" grid. The result is that you can use regular perfboard/breadboard to make shields! We have already gotten much mileage out of this. If you would like to buy Maple without the headers populated, this is available from our website, leaflabs.com
is this what you are looking for? http://leaflabs.com/docs/unix-toolchain.html
would love to see this get done!
raw binaries are uploaded to the board. not ascii/intel hex. However, feel free to rock out in assembly and assemble it into a binary and upload via dfu-util
its actual USB. Our libraries give you a virtual com port (serial) by default over the USB. However, an enterprising programmer and get full control of the USB peripheral and do HID/audio/mass storage/ whatever. We do not have libraries for this yet, but code contributions welcome! github.com/leaflabs
