Welcome to Electron EL-UHF-RMT01’s documentation!

Electron EL-UHF-RMT01 is a UHF RFID Reader with small dimension, low power consumption and 3.3V TTL UART Communication.

EL-UHF-RMT01 consists of an Microcontroller Unit and an antenna which acts as an integrated RFID Reader Writer, and is supposed to be controlled by a computer or another Microcontroller Unit. In this document, the computer or Microcontroller Unit will be called as Host Computer and the EL-UHF-RMT01 will be called as Interrogator.

The UART data format is 8 data bits, no parity, and 1 stop bit (8N1).

Serial communication between the Host Computer and the Interrogator will be documented in hexadecimal. All data in the frame tables are represented in hexadecimal.
