Title: Anyone used a "Sodial" brand Teensy 2.0?
Post by: LifeIsOnTheWire on Tue, 08 November 2016, 07:22:34: https://www.amazon.ca/USB-development-board-keyboard-experiment/dp/B01JFXS2X4/ref=sr_1_6?ie=UTF8&qid=1478610026&sr=8-6

It has an ATMEGA32U4, so it should be able to run TMK or QMK. Can anyone think of a reason this might not be a good idea?

I have an Amazon giftcard, otherwise I would be ordering a PJRC Teensy

What makes the Teensy so special is the bootloader and the high pinout count compared to the ProMicro which sells for ~5$

Thanks for the reply. I haven't flashed a Teensy before. Without the PJRC bootloader, will I run into any difficulty?

How would my flashing experience differ between having a PJRC versus a non-PJRC?

I didn't try to run TMK or QMK because I am programming tennsy in arduino language and for now keyboard matrix work.

Either you want to support the original designers and get the tiny bootloader or you just want a cheap controller that will get the job done, which those should.
