- Rotary Encoder Break Out Board
- STM32 (Blue Pill Board) Microprocessor
- Arduino compatible
- 3.3V
- Si5351 Oscillator Breakout Board
- 10 KHz - 40 MHz tuning range
- 100Hz/1KHz/10KHz/100KHz/1MHz/10MHz steps
- I2C Interface
- 3 Outputs
- 27 MHz crystal

Schematic
Parts
Blue Pill Card
- 3.3V operation works without level shifters for I2C
- OLED runs from 3.3V
- Si5351 can only run from 3.3V
- Used right angle headers and Dupont cables for low profile
- Replaced BOOT 0,1 jumpers
- Wire jumper on BOOT1
- Switch on BOOT0 - easier to download code
- Download via serial
- Programmed via Arduino IDE
128x32 OLED
Libraries/Example Code
Land Boards Code
Used in this app
- U8g2: Library for monochrome displays, version 2
- Si5351 Library for Arduino
- Rotary Encoder - Software debounced
