125kHz RFID TTL base board without a module

The 125kHz RFID TTL Base Board (Without Module) is a dedicated interface board designed for use with 125kHz RFID reader modules. This base board provides TTL-level serial communication, making it easy to connect RFID reader modules to microcontrollers and development platforms.

Designed without the RFID reader module, it allows users to choose and mount their preferred 125kHz RFID module as needed. The board includes clearly labeled pins for power, ground, and TTL TX/RX signals, enabling quick and reliable integration with Arduino, ESP32, STM32, Raspberry Pi, and other embedded systems.

This base board is ideal for access control systems, attendance systems, security projects, and RFID-based identification applications, offering a clean and stable platform for prototyping and product development.
