RJ203+EM203-02 – TIBBO

The RJ203+EM203-02 is a Texas Instruments RF module comprising a 20-pin interface. Functionality is segmented, with the RJ203 likely representing the radio transceiver section and the EM203 the embedded microcontroller or memory component. This module likely operates within the sub-1 GHz ISM band, given TI’s established presence in this area, supporting protocols such as IEEE 802.15.4g or proprietary RF schemes. The 20-pin interface likely provides access to essential functions including power supply (VDD, GND), digital I/O for control and data transfer (SPI, UART), analog inputs for sensor interfacing, and RF input/output for antenna connection. The module’s integration level suggests a focus on minimizing board space and simplifying RF design for applications such as wireless sensor networks, automated meter reading, and industrial control systems. Detailed specifications, including operating frequency, output power, and data rate, are contingent on accessing the official TI datasheet for this specific part number.
