Onehand controller

Controller for onehand only, meant for playing VNs or few input games.

HW info

Design is not yet really implemented, but for build, needed parts are:

Raspberry Pi Pico W (Main controller)
Seeed XIAO nRF52840 (Dongle)
N buttons = 10?
- 4 for action buttons
- 2 for triggers
- turn-off
- special button
- reset button
- BT button
Vibrate motor?
3D printed shell for dongle and controller
- It is expected to have Logitech mouse-like dummy port (where to put dongle when its not used)
- VR controller like holding
- It will, probably, have pretty falic (:gachi:) shape
- Speaker holes and hole for reset button
Battery shell
Status LED, probably RGB one
Speaker? It would be cool
And many wires

For software, following features are expected:

Two connection modes, Dongle (primary) and BT (secondary)
For BT mode, you will need to switch it to BT mode by pressing pairing button
Of course, there will be button (or switch) to turn it on/off
When turned on, it will try to establish private link between himself and dongle
Dongle, when is in PC, it will behave as controller
It will have bindable buttons or prebinded ones, i am more fan of the first one
It will have speaker same as normal controller
It will show status through LED:
- BLUE is BT
- blinking BLUE is pairing BT mode
- WHITE is on
- blinking WHITE is idk // TODO
- RED is error; which type you wanna know? IDK YET! // TODO
