ARDU-5351 VFO full Kit

50kHz to 99.9MHz generator based on the SI5351. It has a variable output and two fixed outputs.

The Arduino code of the Full Kit version (no Open Source) has countless functions and settings. It has a much higher programming level than the Open Source version.

The "full Kit" version includes all the parts to build the complete kit: PCB with all the SMD components installed, pins strips for connections, rotary encoder, SI5351 module and Arduino Nano module (factory programmed).

The "ARDU-5351 VFO full kit" offers many functions and configurations as "Universal VFO" to be used as a local oscillator on a transceiver.

ARDU-5351OS Arduino Open Source. Semi-KIT

Generator from 50kHz to 99.9MHz based on the SI5351. The OS (Open Source) version is intended for programming practices with Arduino and the SI5351 generator. You can download the sketch and modify it for your needs. Downloads. You must have previous programming knowledge with Arduino.

The "OP" version is a Semi Kit that includes: PCB with all SMD components installed, pins strips for connections and rotary encoder (does not include the SI5351 module, Arduino Nano module or OLED display).

An open source program with the following basic functions is offered:

  • A single screen. Without adjustment menus.
  • Outputs: 1 variable and 2 fixed outputs (set on Arduino code).  Steps from 10Hz to 1MHz.
  • Frequency range: from 50kHZ to 99.9MHz (set on Arduino code)
  • Offset IF: 1 IF (set on Arduino code).
