LILYGO has introduced the T-Display S3 Pro, a solution designed for portable applications that require multi-touch display support. This compact device not only boasts a 400mA battery but also integrates a range of sensors and offers optional IMU support.

  • ESP32-S3R8 — Dual-core Xtensa LX7 (up to 240 MHz); 8M PSRAM, 16MB Flash
