As some might have noticed I'm not satisfied with the teensy as MCU and am going to switch to a stm32l4 MCU, I already have the display working, and am going to ditch Bluetooth, because I want to keep it minimalistic.

The tact buttons will be replaced by a capacitive touchscreen, and will behave similar to how Android wear does things (basic gesture control yay!)

Another design change is the whole PCB , I'm aiming for a 34*15mm 4 layer one.

I'm going to try my best to get it somewhat waterproof (pogo pins for charging/programming it using a dock and no buttons should allow me to achieve this.

Also, the teensy 3.2 has no fpu, so alpha blending was veeery slow, this is solved by switching the MCU, giving a boost of 7x at the same MCU clock =)

Anyhow, this is the update for now.
