Hardware Improvements (Thanks to shx for schematic cleanup): - Clean up schematic organization and structure - Set CAN transceiver Silent pin to GND for stability - Add status LEDs (yellow: 24V/5V/3.3V, green: MCU PB4) - Replace jumpers with solder jumpers on bottom side - Add jumpers to output PFETs for permanent-on without firmware - Add robust test points for 5V/GND load testing - Add optional heatsink for DC/DC converter on bottom - Add 10µF capacitor for MCU on 3.3V rail Component Optimizations: - Replace 30kΩ with 33kΩ basic part for simplified BOM - Change DC/DC feedback: 15.5kΩ15kΩ (new output: 5.1V) - Upgrade CAN ESD protection: NUP2105LPESD1CAN - Increase CAN termination resistor footprint: 04020603 - Switch USB hub supply from 5V to 3.3V per datasheet Production Ready: - Add all LCSC part numbers and rotations - Generate complete production data package - Improve PCB layout and button placement - Create comprehensive changelog documentation
