ERRATA FOR 9912 Board Silkscreen Errors: Reference is with the PIC section on the left. Top of Board: C50,C51,C52,C53 missing. They are the 4 caps left of the 9912 just right of the middle shield. R13 missing: R13 is between SW2 and D3 in the PIC section on top. R2 missing: R2 is just above lower left mounting hole left of H3 D1 missing: D1 is just above the H3 designator. FL1 missing: FL1 is at the top of the board above T2. Bottom of Board: C25 is Missing: C25 is at bottom just below U9. C22 is missing: C22 is at bottom just below U6. Connections: In order for the DDS to accept commands from the PIC, CSB must be tied low. A jumper between H7-5(CSB) and H7-5(GND) can be added. Alternately, H7-5 can be connected to a PIC output pin for PIC control of the line. The production board will have a 10K to ground on the CSB line. The footprints for regulators U6 to U12 are a little too wide. The regulators can still be soldered on the board without modifications, but alignment is more critical. The production board has the correct footprints.
