The programming service is EUR 5.00, email or add a note with your order with the frequency (one or two frequencies can be selected by placing the jumper) you need it programmed. If you don't buy the programming service we will send the module not programmed. If you are buying more than 1 controllers, buy just 1 programming, no need to add more.
With OPTION 1: EUR 19.90
The controller board is available with 2 options:
OPTION 1: With the ECS-TXO-3225-100 TCXO (10 MHZ) which has 2.5ppm stability (as specified in its datasheet)
OPTION 2: With the LFTVXO075802CUTT TCXO (10 MHZ) which is specified at 0.28 ppm stability and it is much more expensive.
Please select when ordering, the only difference is on the TCXO used.
The KIT includes a high-quality ENIG FR4 PCB (25 x 38 mm) that comes with all SMD components factory pre-soldered. RF capacitors are used for all the circuits.
Three SMA female connectors (long shaft) with nuts and washers are also supplied, unsoldered.
The shipping is with registered mail (your signature is required upon delivery).
I usually ship the next day and it takes about a week to 10 days for USA or Australia, less than a week for Europe.
If you will use an external reference you can deactivate the board's TCXO by removing either L1 and or R3
I have found this "cheat sheet" that helps, see it here:

NEW: Controller PCB for the ADF4351M PLL Synthesizer PCB Module for fixed frequency
ATtinny-85 micro-controller with 3.3VDC Voltage Regulator to supply the ADF4351M and Reference TCXO on a same size PCB module for set and forget installations. A second frequency is selectable with jumper JP1. ATtinny's ISP connector on board (J3) to develop your own applications.
Programming Service at EUR 5.00:
Please mention your frequencies while ordering and we will deliver with the firmware installed.
With OPTION 2: EUR 29.90
The ADF4351 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and external reference frequency if the on-board 10 MHZ is not used. The ADF4351 has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency ranging from 2200 MHz to 4400 MHz. In addition, divide-by-1/-2/-4/-8/-16/-32/-64 circuits allow the user to generate RF output frequencies as low as 35 MHz. Control of all on-chip registers is through a simple 3-wire interface. The ADF4351 module draws under 60 mA - 100 at 3.3 VDC, depending on the output power set and if the frequency dividers are being used.
The PCB dimensions are only 25 x 38 mm and it requires an external frequency reference that can be applied to J5 SMA female connector if the on-board 10 MHZ TCXO is not used. In this case remove L7 which powers the TCXO with 3.3VDC.
A small Arduino or any other MCU can be used to control the ADF4351 module, and the "cheat sheet" provided at the end of this page is really a great help. Considering its small size and the simplicity this module provides, a user can quickly produce an RF signal, phase-locked to his reference and also to control the output power, this module can find many applications like a VFO, fixed frequency oscillator, ADC or DAC clock etc. Interesting features are the capability to adjust phase, to set low spur or low noise and of course the capability to select Integer-N for lowest phase noise. Adding a large capacitor on the supply rails reduces phase noise more.
