ARDU-5351 VFO

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

The Arduino code has countless functions and settings. It has a much higher programming level.

All 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" offers many functions and configurations as "Universal VFO" to be used as a local oscillator on a single band transceiver.

Note: A basic Arduino-5351 sketch open source code intended for teaching can be downloaded from the Firmware-Updates section. (use a new Arduino module, don't use the original module from the kit!).

OLED display sizes, 1.3" (20x35mm window).

Note: By default, the signal output is about 4-5dBm. This level is more than enough for active mixers (NE/SA602 or similar). If you need the maximum output of the SI5351 (about 8-10dBm) for passive mixers etc, please indicate this in the comments when ordering. We will program for it.

ARDU-5351 mini VFO (no display, frequency announced in CW

• One variable frequency output + one fixed output (IF/ BFO)

• Easy setup using the Arduino IDE Series Monitor.

• Control: Simple control through a encoder with push button.

• Output frequency information by audible tone in CW code (three digits)

• Frequency output range: 50kHz to 99.9MHz

• Automatic frequency save function.

• Frequency steps select by encoder push/button. Steps: 1kHz, 100Hz, 10Hz. 

• IF offset function. Offset IF: VFO = F + IF, VFO = F + IF, VFO = IF – F, OFFSET = 0. 

• Adjustable mínimum and maximum frequencies

• Easy assembly by clamping the rotary encoder shaft

• All SMD parts are soldered. 

• Power supply: 7 to 15V DC. Average current consumption: 50mA.

• PCB size: 55 x 30 mm
