T-Embed get it now

Overview

LILYGO T-Embed is a multi-functional ESP32-S3 development platform featuring a 1.9-inch ST7789V IPS TFT (320 × 170), a 24-step rotary encoder, 7 APA102 RGB LEDs, a stereo speaker (MAX98357A I2S amplifier), dual MEMS microphones, and a MicroSD card slot. Powered by the ESP32-S3 dual-core LX7 @ 240 MHz with Wi-Fi and Bluetooth 5.0, it includes a 3.7 V Li-Po battery port and a 1300 mAh battery. Suitable for audio players, smart remote controls, LVGL-based HMI interfaces, and embedded IoT hubs.
