RC08ProtoErrata
From GT RoboJackets
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 SOT223new switcher means new diodes... -
FLASH should be SO8ordered - Power switch footprint is incorrect
- 10uF caps are 0603 should be 0805
-
0.1 uF from SRST to GND on ARMfixed -
Pullup for the base of the buzzer transistorfixed -
TRST on ARM needs a pullupfixed -
WR needs to find a new pin on the ARMfixed? may move for layout reasons -
Mode2 Should go to jumperfixed -
Mode1 Should be tied lowfixed -
DONE should be pulled to 2V5fixed -
PROGB should be pulled to 2V5fixed
Feature Requests
- 0603 pkg for diodes
-
Connect SRST to JTAG Connector -
Notch filter for RX/TXantenna 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
