T-Display S3 Long: ESP32-S3 with 3.4inch Capacitive Touch TFT LCD (shell not included)- LILYGO® H685

Embedded electronics specialist LILYGO has launched a new development board based on the Espressif ESP32-S3 system-on-chip, and this one's for anyone who struggles to squeeze a user interface into a narrower layout: the ultra-wide T-Display S3 Long.

The T-Display S3 Long, is built around the Espressif ESP32-S3R8 system-on-chip — giving it a 32-bit dual-core Tensilica Xtensa LX7 processor running at up to 240MHz, vector extensions for improved performance of on-device machine learning and artificial intelligence (AL and ML) workloads, 512kB of static RAM (SRAM) and a further 8MB of pseudo-static RAM (PSRAM) off-chip — plus 16MB of off-chip SPI flash storage.
