Though the $35 special is only good for 1 unit per person, Synergy offers a 10% educational/ham radio/experimenter discount for additional/subsequent units bringing the price to around $63 for time-nuts who need more than 1. I'm thinking the other unit they have announced (without the PIC) should be even cheaper. Maybe if we are real nice they will offer a single unit special price on that one when it comes out early next year.

He said, if my ancient memory serves, that the PIC on the new board will be available for programming, and that it might be possible to do an ONCORE as a software conversion from the UBLOX to the output connector. Just who is going to do this, not sure. But it will be possible. The newer versions of the SST will be programmable through the serial port. At present, the extra side port on the board is a programming connector. The info will be on Synergy's SST website. Even at $70 per, a UBLOX timer and PIC on the same board might be very cost-effective for all sorts of fooling around!

Does anyone have the pin-out for the 5-pin connector on this board? The 10-pin connector is documented, but not the single-in-line 5-pin connector near the label HGR200 (?). I didn't see it documented in this thread either.

That header is used for programming the on board PIC. I've rung it out as follows: Header pin 1 -> PIC pin 18 MCLR (active low) Header pin 2 -> PIC pins 28 & 40 VDD Header pin 3 -> PIC pins 29 & 39 VSS Header pin 4 -> PIC pin 21 PGD1 Header pin 5 -> PIC pin 22 PGC1 73 Dale NV8U Sent from my iPhone On Jan 5, 2013, at 6:46 AM, "David J Taylor" <david-taylor@blueyonder.co.uk> wrote: > Does anyone have the pin-out for the 5-pin connector on this board?

Thanks for mapping that out Dale. I'm sure it's no coincidence that that pinout is the same as that of Microchip's PICkit3 (et al.) programmer. 73, Brent, KD0GLS, Minneapolis On 5 Jan 2013, at 11:38, Dale J.
