JustStan bf32b28266 Standardize repo: .gitignore, README, license, remove production from tracking

- Standardize .gitignore to match ecosystem template
- Fix README: remove stale Radioschematic ref, fix 10V→12V, remove generic sections
- Replace LICENSE stub with full CERN-OHL-S-2.0 text
- Remove production/ from git tracking (generated, re-exportable)
- Untrack generated files: OpenFC.net, replicate_layout.log, ibom, old render

OpenFC

Open-source Betaflight flight controller with integrated break-off ELRS receiver, based on the RP2354B microcontroller.

Features

Microcontroller

RP2354B - Raspberry Pi dual-core ARM Cortex-M33 @ 150MHz (with integrated flash)

Integrated ELRS Receiver (Break-off)

On-board 2.4GHz ExpressLRS receiver module
Break-off design allows for different placement if needed

Sensors

IMU: LSM6DSV16XTR
Barometer: BMP388

Blackbox Data Logging

BY25Q128ASWIG - 128Mbit (16MB)

Motor Outputs

4x PWM/DShot motor outputs

Analog OSD on PIO

Hardware implementation of opamp and mux to detect syncs and select between white and black pixels. Needs software implementation still.

Connectivity

USB-C - Configuration and firmware flashing
UART0 - Serial RX/TX (ELRS connection pads)
UART1 - Spare serial port
PIO UART - Software UART via RP2350 PIO (2x)
I2C - External sensor expansion
SPI - IMU and Blackbox on isolated bus.

Analog Inputs

Current sensor input (ADC)
RSSI input (ADC)
1 external available ADC input

Additional Features

Addressable LED strip output (WS2812/NeoPixel)
Buzzer output
16 LED's built in on corners
ELRS ESP flashable by the RP2354B (BOOT/EN pins connected)

Power

2S-6S batteries
12V and 5V regulated outputs, 12V is switchable
