Changes

  • Stepper Driver Improvements
    • Fix stepper driver SPI pinout (#17, #23)
    • Add support for TMC2208/2209 UART interface
    • Add support for TMC StallGuard DIAG signal
    • Replace VMOT protection diode with P-FET to reduce voltage drop
  • Endstop Improvements
    • Add RC filter (10K/2.2nF) to each endstop to filter/debounce + provide ESD and overvoltage protection
    • Add pull-up resistor to each endstop
    • Add solder jumper for selecting endstop voltage (5V or 3.3V - defaults to 3.3V)
  • Thermistor Improvements
    • Add series resistor to thermistor signal, forming RC filter with existing capacitor to filter + provide ESD protection
  • Add servo header
    • Pin PA15 dedicated to servo use + also supports hardware PWM
  • Overhaul 5V Power Supply:
    • Replace AOZ1292 with AP63205
    • Maximum current available increased from 1.2A to 2A
    • Synchronous regulator improves efficiency
  • Rework auxiliary power header
    • Add header for 5V output directly from 5V regulator
    • Make header strip for auxiliary power continuous (VIN, 12V, 5VDC, 5V, 3.3V)
  • Add I2C EEPROM
    • 24LC64T-I/OT (8kB) added to board
  • Make space for above changes
    • Change most passives to 0402 size
    • Remove unused user button
    • Remove 2 x I2C headers (2 remain)
