EEI TECHNOLOGY VFD40-1603 VFD power amplifier spectrum 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.
• All gates are equipped with current amplification circuits to solve the uneven brightness caused by insufficient output current of the driver chip.
• 8 levels of brightness adjustable.
• The maximum power consumption is about 4W (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.
• The screen can be removed from most equalizers (you can use BOE's VFD40 series (VFD40-1601 VFD40-1602 VFD40-1603 VFD40-1604) and FUTABA's BG-900GK. The anode connections of these screens are the same) .
• Equalizers (some models) using the above screens include Pioneer MC-930 950 950K 960 960K and Qisheng SGE-777. Buying a second-hand one from Xianyu costs tens of yuan, and the screen alone costs almost 20.

Notice!

• 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!
