## [Unreleased]
### Changed
- **Production:** Test points TP202/TP203 excluded from BOM
- **JLCPCB Optimization:** Rotation offsets adjusted for automated assembly
- U202/U301: FT Rotation Offset 270°
- U401: FT Rotation Offset 180°
### Technical Details
- **Manufacturing Efficiency:** Optimized component orientation reduces production time
## [Rev. 0.3] - 2025-12-09
### Added
- **CAN Transceiver:** 10µF capacitor C304 for improved CAN communication stability
- **PCB Layout:** QR code placeholder for serial number on the PCB
### Technical Details
- **Enhanced Signal Integrity:** Additional filtering at CAN transceiver for more stable data transmission
- **Traceability:** QR code enables unique identification and documentation
## [Rev. 0.2] - 2025-12-08
### Improvements
- **Schematic:** Cleaned up and structured (Thanks to "shx")
- **CAN Transceiver:** Silent pin connected to GND for better stability (Thanks to "shx")
### Added
- **Status LEDs:**
- Yellow LEDs for 24V, 5V and 3.3V voltage indication
- Green LED on microcontroller (Pin PB4)
- **Solder Jumpers:** Replaced standard jumpers with solder jumpers on bottom side
- **PFET Control:** Added jumpers for output PFETs - enables permanent-on without firmware
- **Test Points:** Added robust test points for 5V and GND for load testing
- **Heatsink:** Optional heatsink for DC/DC converter on bottom side
- **MCU Capacitor:** 10µF capacitor for microcontroller on 3.3V rail
### Changed
- **Production:** Added all LCSC part numbers, defined rotations, created production data
- **PCB Layout:**
- Adjusted according to schematic changes
- Improved button positioning
- **BOM Optimized:**
- Replaced 30kΩ with basic part 33kΩ
- Changed 15.5kΩ DC/DC feedback to 15kΩ → new output voltage: 5.1V
- **CAN ESD Protection:** Replaced NUP2105L with PESD1CAN (better suited)
- **CAN Termination Resistor:** Changed footprint from 0402 to 0603 for adequate power rating
