Lilygo’s T-Embed: A Compact IoT Embedded Panel with ESP32-S3, RGB Ring Light, and TFT Display

Lilygo has recently launched the T-Embed, an IoT-embedded panel designed for programmable development, featuring a compact design with ABS and PC material. The ESP32-S3 MCU powers it and supports Wi-Fi and Bluetooth 5, including Bluetooth mesh. The panel includes a 1.9-inch IPS color TFT LCD (ST7789 model) with 170×320 resolution, offering clear visual output at 350 cd/m2 brightness. It also has dual microphones, a speaker (8 ohms at 1W), a microSD, and a rotary encoder with a confirmation key. This device has an RGB ring light, a GROVER connector, a GPIO interface, and a Type-C USB port.

Additionally, it has a battery charging and discharging protection circuit. This device is perfect for building internet-connected devices (IoT and programmable devices). It is good for people who want to create IoT projects with screens and buttons. It is straightforward with drawings and code examples, so it is good for smart devices or IoT projects.

We have previously covered some similar ESP32-S3-based IoT products, such as Lilygo’s T-TWR REV2.1, Lilygo’s T-Encoder pro, Waveshare Matrix Dev Board, and many more.
