[Chat] I'm Tomu - A tiny ARM microprocessor which fits *inside* your USB port (for U2F or other tasks)

[Tim Ansell]

I still have ~25 Tomu boards left and will be around until the LCA2017
closing.  I'll be in the MicroPython on FPGA BOF (
https://linux.conf.au/wiki/conference/birds_of_a_feather_sessions/micropython_on_FPGAs/)
and giving a lightning talk at the closing.

Last chance to get your preconstructed Tomu! Send pull request or $10 AUD
to get one.
