Revision
Notable Changes
C
- Initial release of the board
D
- R31 to R38 are changed to NA, because into the newest GL850G
datasheet(schematic) they are removed
- In addition PSELF is connected to V33 pin through 10k resistor
with the aim of GL850G to be set in self-powered mode
- Altered inductors: L1,L2 i L5 to 7x8mm package.
- All capacitors 22uF/0805 are now changed to 22uF/0603
- Added prints of the names of WIFI and PGM_FUSES connectors
- New powering scheme with jumpers for the WIFI
- Removed FET1 due to resistance and because TVS works also as a
protection
- PWR_LED and LED1 were too bright, the resistor is now 2.2k
- WIFI connector has been moved with 1mm near the quartz so it is
far enough from the capacitors
- Added 100k pull-down resistor on the debug line. According to
the IMX23RM, page 1368:
If the DEBUG pin is unused, Freescale recommends pulling the
DEBUG pin to ground through a 100K resistor.
- Changed the text DEBUD to DEBUG into the SJTAG's connector
bottom silk.
- Added Schottky diode and increased R9 to 4.7K because of bug
that might appear if using
- Added C75(10pF)
- Added ferrite bead 2A on the 4
th
USB of the hub also (wifi only)
E
- Moved the print of the names of PWR_JACK and 6-16VDC since they
were overlapping; The Composite Video print is also adjusted.
LINE_IN and HEADPHONES are also moved a bit. R44 and R55 too.
- The jumpers SW_SCL/HW_SCL and SW_SDA/HW_SDA position is changed
to default HW (hardware SCL)
- PGM_FUSES line is changed 10mils to the upper side, C48 is
moved 5mils to the bottom edge.
