FlatPort

Teensy 2.0 Risc-V dropin Arduino promicro lookalike with special features. The chip I used is GD32 VF 103 CBT6 from Giga Device.

It has a in-plane Type-C USB receptacle - it does not show much but it doubles as a full featured Type-C port - in this case a reversible USB 2.0 spec port only.

It also features in-plane Reset and Boot0 tasters - they are shorted by touching with a pointy conductive/metal object.
Do note they are not to be touched mutually by a same metal object: one shorts pin Boot0 to ground the other pulls the reset pin to Vcc.
In effect this means one of the contacts is gound and the other is Vcc - shorting them mutually would blow the fuse!

I picked to make this project for the alleged compatibility with QMK firmware - to be a future keyboard daughter board. As I get to that point expect more updates here, it is on my ever growing TODO list :o}
