Hello,
I recently put together this little board, and I'd love to get feedback!
Thanks!

I recently put together this little board, and I'd love to get feedback!
- It should have 100% software & functionality compatibility with the Teensy 3.2
- It's programmable via Teensy Loader or Teensyduino via Arduino (via official PJRC bootloader)
- Programmed via USB with a custom/simple/tiny/cheap micro USB cable to 5x pogo pin adapter
- Overall size is exactly 30 x 30 mm, 56-pins (4 sides x 14), 2.0 mm pitch, 1.0 mm thick PCB
- Exposes all equivalent Teensy 3.2 pins, including all of its underside pins
- Designed for a surface-mount landing pattern, no through holes necessary
- Can be reflowed in place, also large enough to be soldered by hand
- Design has been assembled, verified working well enough to program the chip and run blink code
- Has an integrated 32.768 kHz RTC crystal
- Do you see utility in this?
- How much would you want to pay for something like this?
- Should it be even smaller? There's room, since the passives are 0603 and still have plenty of space between them. I'd have to reduce the pitch to 1.5, 1.27, or 1.0 mm, which could make hand-soldering the board in place much more difficult.
- Do you think there will be any problems regarding re-reflowing this onto another PCB? If so, any ideas about how this could be potentially mitigated?
- Is there any interest in a 3.5 or 3.6 version of this sort of thing?
- Is there anything else you'd like to see included onboard?
- Is around $10 a reasonable cost for the USB to pogo programming adapter?
Thanks!
Dan
