Features
- SDD1306 OLED Display
- I2C Interface
- OLED runs from 3.3V (can run from 5V but this use has 3.3V)
- Rotary Encoder Break Out Board
- Arduino Pro Mini
- Arduino compatible
- 3.3V
- 8 MHz
- Programmed via Arduino IDE
- Download via serial
- Si5351 Oscillator Breakout Board
- 10 KHz - 40 MHz tuning range
- 1Hz/10Hz/100Hz/1KHz/10KHz/100KHz/1MHz/10MHz steps
- I2C Interface
- 3 Outputs
- 27 MHz crystal
- 3.3V operation works without level shifters for I2C*
- Si5351 can only run from 3.3V
- Used right angle headers and Dupont cables for low profile
- 10 KHz - 40 MHz tuning range
- Mini-360 Buck Regulator
- 5V-23V input
- 3.3V output
- Extruded Aluminum Enclosure Box - 94mm x 83mm x 30mm - Out of stock
Schematic
- PWR* - connect only when no Mini-360 Buck Regulator is used
Build
- Extruded Aluminum Enclosure Box - 94mm x 83mm x 30mm - Out of stock
- BNC/Power Jack placement
- Rear panel BNCs and power jack
- Drill holes and nibble out for OLED cutout
- A bit rough
- Better to undercut nibble and file to size
- OLED fitted
- Final
Libraries/Example Code
Land Boards Code
