PCB rev.A
|
|
|
|
|
---------
|
|
|
|
|
Add diode 1N4148 after R18 into P2, minus facing R18.
|
|
|
|
|
|
|
|
|
|
Fix switches SW1-4, connections wrong. Check libraries
|
|
|
|
|
connection between schematic and pcb.
|
|
|
|
|
|
|
|
|
|
Fix FT232 power, skip crystal X1 and C3. VCC must come
|
|
|
|
|
straigh from the USB connector while VCCIO connects
|
|
|
|
|
straight to 3.3V, skip JP1 and JP2.
|
|
|
|
|
|
|
|
|
|
LED's D2 and D3 are in the wrong pins, move them to pin 13(PB1)
|
|
|
|
|
and pin 14(PB2), no specific order, whatever is best for routing.

Remove R7 and R8, replace with track.
|
|
|
|
|
|
|
|
|
|
Vbatt voltage divider, the 3 resistors R10, R11, R12 need to be moved
|
|
|
|
|
to the other leg of R13 and values re-calculated.
