Contents
Features
- DD1306 OLED Display
- I2C Interface
- Rotary Encoder
- Blue Pill Microprocessor
- Arduino compatible
- 3.3V
- Si5351 Oscillator
- 10/100/1KHz/10KHz/100KHz/1MHz steps
- I2C Interface
- 3 Outputs

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
Arduino Library for OLED
U8G2_SSD1306_128X32_UNIVISION_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE); // STM32, Ebay OLED
u8g2.setFont(u8g2_font_ncenB14_tr);
Hello World Code
U8G2_SSD1306_128X32_UNIVISION_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE); // STM32, Ebay OLED
void setup(void) {
u8g2.begin();
}
void loop(void) {
u8g2.clearBuffer(); // clear the internal memory
u8g2.setFont(u8g2_font_ncenB08_tr); // choose a suitable font
u8g2.drawStr(0,10,"Hello World!"); // write something to the internal memory
u8g2.sendBuffer(); // transfer internal memory to the display
delay(1000);
}
Rotary Encoder/Breakout Board
- Includes pushbutton Switch
- Includes Pull-Up resistors
- Needs R/C filter on output for debounce

- Simple Rotary Encoder Arduino library
- Library for the Arduino environment for using a rotary encoder as an input
Si5351 Frequency Generator
- I2C Daisy-chain connector
- 3 outputs
- Heat shrinked assembly with cables
Measurements
- 10 MHz FFT
- Square wave has high odd harmonic content
