There are plans to update this project and to implement new features (roadmap for 2022):

GEN2.1:

- mechanical improvements (new PCB dimensions, updated mounting holes position),

- updated GPIO port to be compatible with future designed LCD front-panel,

- designed dedicated push-button controller and power management unit (PMIC).

GEN3.0:

- PoE power supply standard,

- LCD front-panel with 3.5" screen and touch pad,

- fingerprint sensor,

- NFC reader,

- 12VDC power supply,

- 2-port USB hub.

#BitPiRat during testing...

CM4 & CM4 Lite - OK
MiniHDMI - OK
Qwiic OLED - OK
User LEDs OK
Buzzer - OK
ETH - OK
M.2 NVMe SSD 2280 - OK
PWM fan EMC2301 - OK
USB 2.0 - OK
MIPI DSI - OK

It seems that so far all the features are working 100%

Waveshare LCD module: 1.3", 240x240 pix, IPS matrix, ST7789 controller.

You can connect lot of different LCD/OLED screens by using interfaces such as: I2C, SPI, MIPI DSI, or MiniHDMI.

So you can also run OS @RaspiBlitz @mynodebtc @RoninDojo

Setup:
- CM4 Lite module with 8GB RAM,
- 1TB NVMe SSD drive (WD Blue SN550 Series),
- 64GB microsd card (SanDisk Extreme),
- GbE,
- 5.1V supply

OK, 100%, fully synchronized.
Citadel updated to v0.5.17.
Node works stable and without any issues so far.
