  • Four layer design with two inner uninterupted ground planes.
  • USB-C connector.
  • CAN pin header.

Specs

  • Input: +3.52V to +5.25V
  • Output: +3.3V @ 1000mA
  • Dimensions: 53.8 x 19.4 mm
  • Headers: 2, 20x0.1in pins @ 0.6in spacing
  • Schematic
  • 8 Mhz oscillator
  • LM1117 LDO Voltage Regulator (datasheet)

Pins to MP2

VERSIONS:

  • The F405_pill_V1.0 has been deprecated.
  • The F405_pill_V1.11 has an additional 100nF cap on the input to PA4 (throttle) and we suggest you use this for ordering.

V1.1 changes

  • Xtal caps from 18pF to 12pF
  • Separate the two LEDs from the single resistor
  • CAN spike protection
  • RC between GND and pb12 to stop false trips
  • PC12->PA15 to drive LED
  • Increased functionality of several header pins
  • Review this document for pin changes

REVISION REQUEST

  • Jumper to disable CAN termination resistor on bottom side of board
