Isolated 10Mhz distribution Board and Free PCB, Truepostion GPSDO

[RoadRunner]

After receiving free PCB from a nice forum Member. i have decided to give away few PCB i have that other may find useful.

I made my self distribution board for My GPSDO, here the project
https://www.circuitvalley.com/2018/07/diy-isolated-10mhz-distribution-amp-gpsdo-rubidium-tcxo-reference.html

i have made two revision of board because oscillator i have is giving not very clean sine wave so i made second revision of the with more passes of LC filter.

Board has PIC18F25K50 based USB to serial / GPSDO Controller firmware for TruePosition GPSDO.

i have minimum 8 of V1.0 PCB and 2 or 3 V1.1 bare PCBs to give away, to any one who ask for it , To have little confidence that Taker will have some use in mind. Taker will pay original shipping , it can be shipped in envelope For 0,85 EUR within Germany , and 1.50 EUR to any other country. i can ship worldwide with few exception.


I do have few assembled V1.1 boards as well, if anybody interested for 75EUR. BOM cost of board is very high because transformer, Nice connectors and opamp. all the components only source from mouser or arrow, "no ebay part Guarantee".

Here is Source, and BOM of V1.1 PCB
https://github.com/circuitvalley/trueposition_gpsdo_usb_oled/tree/master/Hardware_Schematic_PCB/Isolated%20Distribution%20Amp

I do have few extra TruePosition board assembled in Hammond enclosure with, Trimble GPS antenna,Power supply. For 185 EUR
Here is how assembled unit looks. All gone

Hi RoadRunner,

I recently bought and tested a TruePosition GPSDO and actually was looking to build something along the lines of Your project.

So I would be very happy to have one of Your v1.1 PCBs.

Cheers,
Zigmars

Received today one of these, it's really a nice unit. Does its job as I expected it to, and saved me a lot of effort to build my own box around a GPSDO unit.
You did a good job Roadrunner, thanks!
