GP1287BI VFD display module (UNL-200AP)

#EEI TECHNOLOGY 05P-FLUORITE UNL-200AP Universal VFD display module

* **Has a wide voltage input range of 4.5-20V. **
* **Adaptive 3.3V/5V level (compatible with 51, STM32 and other mainstream microcontrollers). **
* **Improved power supply and filament driving scheme, no whistling and more efficient. **
* **The VFD screen has a built-in timing controller, which effectively avoids screen burn-in caused by improper use. **
* **1024 levels of brightness adjustable. **
* **The maximum power consumption is about 6W (full lighting, 1024 brightness, 5V input). **
* ** Built-in dynamic scanning logic and RAM, you only need to send instructions to the screen to complete the display. **
* **Reserve the main control board position on the PCB to effectively utilize the free space. **
* **The audio input interface is reserved to facilitate audio applications. **
* **Onboard photoresistor, with microcontroller, can achieve automatic brightness. **
* **TYPEC and DC005 power interface, suitable for various power supplies. **

## Precautions

* **The driver board has high voltage, please operate with caution. **
* ** U8G2 project (STM32CubeIDE) is provided. Due to my poor programming skills, I cannot develop other drivers. If necessary, please develop it yourself. **
* **U8G2 project pin description: PA5 SCK, PA7 SDA, PA1 CS, PA3 RESET**
