As we find board errata on the Prototype 1.0 (marked Feb 22 2008) they are listed below

Errata

  • 3V3 Switcher diode is DPAK, should be SOT223 new switcher means new diodes...
  • FLASH should be SO8 ordered
  • Power switch footprint is incorrect
  • 10uF caps are 0603 should be 0805
  • 0.1 uF from SRST to GND on ARM fixed
  • Pullup for the base of the buzzer transistor fixed
  • TRST on ARM needs a pullup fixed
  • WR needs to find a new pin on the ARM fixed? may move for layout reasons
  • Mode2 Should go to jumper fixed
  • Mode1 Should be tied low fixed
  • DONE should be pulled to 2V5 fixed
  • PROGB should be pulled to 2V5 fixed

Feature Requests

  • 0603 pkg for diodes
  • Connect SRST to JTAG Connector
  • Notch filter for RX/TX antenna switch?
  • New 3V3 supply
  • Smaller 1V2, 1V8, 2V5 supply
  • 10A Fuse
  • Bigger motor caps (>150uF) We can fit panasonic F on panasonic E pads (just taller formfactor). We will get 470uF.
  • Cap by power input (470uF)
  • Schottky diode on input to 3V3 rail, bigger input cap
