Contents
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
- STM32 (Blue Pill Board) Microprocessor
- Arduino compatible
- 3.3V
- Replaced BOOT 0,1 jumpers
- Wire jumper on BOOT1
- Switch on BOOT0 - easier to download code
- Programmed via Arduino IDE
- Download via serial
- Si5351 Oscillator Breakout Board
- 10 KHz - 40 MHz tuning range
- 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
- Extruded Aluminum Enclosure Box - 94mm x 83mm x 30mm - Out of stock
