  edi released this 2025-12-08 10:11:39 +00:00 | 2 commits to main since this release

  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
