Generator from 50kHz to 99.9MHz based on the SI5351. The OP (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. You have to 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 functions is offered:
50kHz to 99.9MHz generator based on the SI5351. It has a variable output and two fixed outputs.
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.
