EEI TECHNOLOGY HNA-16MM64 VFD power amplifier display module

• Features a wide voltage input range of 5-24V.
• Onboard level conversion chip, adaptive to 3.3V/5V level (compatible with 51, STM32 and other mainstream microcontrollers).
• The improved Cuk negative pressure and filament driving scheme has lower power consumption and more uniform brightness.
• Use professional VFD dot matrix driver chip, built-in font library, and 8 custom symbol spaces.
• 8 levels of brightness adjustable.
• The maximum power consumption is about 2.65W (full brightness, 15/16 pulse width, 5V input).
• Built-in dynamic scanning logic and RAM, you only need to send instructions to the driver chip to complete the display.
• You can buy the screen from the manufacturer (Shanghai Pufeng Optoelectronics) at a cheap price.

Notice

• PT6302LQ is not resistant to high temperatures. Do not use a hot air gun to solder directly from the front! !
• The big and small endian of the initialization command of PT6302 and the font command are opposite, so you must pay attention when using them.
• This project is for DIY and learning purposes only. Any sale, dissemination, or copying of this open source project for commercial purposes is prohibited (including modifying its frame and silk-screening it for sale).
• Investigate all piracy and counterfeiting (recently, it was discovered that a second-hand dealer deleted the "EEI TECHNOLOG" LOGO on an e-commerce platform and copied the board number and version number format of EEI TECHNOLOGY for sale, which has had a bad impact on my studio). For this kind of behavior , we will crack down severely when necessary!
