Teensylu V1 is now officially on the Reprap.org Wiki.

Nice! Now please please say you’re using a different ID from pjrc.
What do you mean by ID? USB-ID? That’s not up to me. I develop hardware. The mcu comes with whatever settings and bootloader that Atmel uses. It leverages the work that pjrc did in implementing an arduino library, but thats all on the firmware side.
I’m also working on the espressylu, a 32bit version of the TeensyluV1.
@Stephanie_A Yep, I mean USB-ID. And although that’s sort of the responsibility of whoever develops the firmware and decides which bootloader to use, it has potential hardware repercussions. Namely, if the firmware goes with an existing USB-ID and someone uses the same computer to do 3D printing and microcontroller development, there is a nonzero chance that an upload intended for the bare microcontroller will go to the printer instead, with unpredictable results.
I have the remains of a hotend to remind me not to print and program at the same time (unless over the network with octoprint).
The at90usb1286 comes with a dfu bootloader, which requires a jumper to be set on the board to put it into programming mode. If you have 2 devices connected, both set to bootloader mode, then you need to slow down and work on one thing at a time.
This board was designed specifically to address the safety issues of reprap control boards. It is designed with more safety features than your average low cost controller (which happens to be the original teensylu).
More safety features is good. (The board I was using at the time had an At90usb1286 on it but identified itself as having the same ID as a pjrc Teensy, and appeared to respond in a way that satisfied the Teensyduino uploader. It’s possible that it wasn’t actually being reprogrammed and just thought it was receiving some really bad Gcode that put it in a state not fixable by power-cycling.)
the best board I have ever used (until last week, that my new Duet arrived. thumbs up for the espressilu!
I have crappy soldering skills…too bad you aren’t selling these things @Stephanie_A …or are you?
I usually only build prototypes. I don’t have the money for it right now. I can solder anything though.
I can do what I do for Peter…donate ‘beer and popcorn money’ for a board…
It’ll still need to wait, to get anything at a reasonable price, I need to buy in bulk. It all adds up to a few hundred dollars to build 10 or so boards (not including stepper drivers). Being a poor hardware developer sucks.
Well, I do have many printers. So what’s a ‘few hundred’? 2, 3, 4? More importantly, if I bought the inventory of parts, and you made 10 boards, would you make anything worth your time if I financed the buy. I’m doing something like this for the OpenCNC and P3 Steel
I’ll need to investigate the cost. Discounts start at 10 units, but there are multiple of the same part per board.
Ok, well, I do have 4 printers sitting in project boxes waiting to be built so let me know
