T-Embed SI4732

Introduction

LILYGO T-Embed SI4732 is an enhanced version of the base T-Embed, featuring an integrated SI4732 extension module. The SI4732 is a high-performance digital-tuning radio receiver chip, designed for AM/FM/SW/LW broadcast band reception. It incorporates Digital Signal Processing (DSP) technology, offering high sensitivity, low power consumption, and high integration, making it ideal for a variety of radio and audio applications.

As for the T-Embed base board itself, it features a rounded rectangular design and integrates a rotary encoder with RGB LED ring and a 1.9-inch IPS TFT display. It also includes a MEMS microphone array, built-in speaker, internal TF card slot, and power management circuitry, supporting 3.7V lithium battery power. Expansion options include both a GROVE port and a 2.54mm-pitch GPIO header, offering flexible connectivity for development and prototyping.
