125KHz RFID Reader Module (5V) – Standalone DIY Access Control Kit

Upgrade your interface with crisp visuals.
This 12864 Graphic LCD Module delivers a sharp 128x64 pixel resolution on a stunning blue backlight with white pixels. Built with the versatile ST7920 controller, it supports both Parallel and SPI Serial modes, allowing you to save precious I/O pins on your Arduino or microcontroller. Perfect for displaying complex graphics, charts, and custom text.

• High-Res Graphic Display: 128x64 dot matrix resolution enables text, images, and graph rendering.
• Crisp Visibility: Deep blue background with bright white pixels provides excellent contrast and aesthetics.
• Dual Interface Modes: Supports both 6800 8-bit Parallel and Serial (SPI) modes (Selectable via Pin 15 PSB).
• Standard 5V Logic: Seamlessly compatible with Arduino UNO, Mega, and other 5V logic controllers.
• Adjustable Contrast: Dedicated V0 pin allows for precise brightness and contrast tuning via potentiometer.
• Robust Mounting: Four corner mounting holes (3mm) for secure installation in enclosures.

Simplify Your Security Projects with the YS-RFID2

Are you looking to add keycard security to your project but don't want to write hundreds of lines of code? The YS-RFID2 125KHz RFID Module is the ultimate "set-and-forget" solution for makers and technicians.

Unlike standard RFID readers that require a microcontroller (like an Arduino) to process data, this intelligent standalone module handles everything on-board. It features a built-in microcontroller (STC15) that memorizes card IDs, meaning it works independently once powered up.

How It Solves Your Problem

• No Programming Needed: Features a simple "KEY" button on the board. Press it to register a card; long-press to wipe the memory. It’s that easy.
• Direct Control: When a registered card is swiped, the OUT pin sends a High-Level (4.3V) signal. You can connect this directly to a Relay Module to unlock a door, turn on a light, or activate a motor.
• Versatile Application: While it works great standalone, advanced users can modify the solder pads to change modes (Toggle Mode/Self-Lock or 10-Second Delay), making it adaptable for any scenario.

Professional Grade Reliability

Built with a TI LM258 chip and a strong anti-interference MCU, this module offers stable reading distances of up to 3cm (depending on card size). Whether you are retrofitting a garage door, building a secure storage box, or teaching students about RF technology, this module delivers consistent performance.
