T4-S3 ESP32-S3R8 Touch Screen 2.41-inch SPI RGB AMOLED - LILYGO® H678


In the realm of microcontroller development boards, the LILYGO T4-S3 stands out with its unique combination of a 2.41-inch AMOLED touchscreen display and the powerful ESP32-S3R8 microcontroller. This board is not just another entry in the ESP32-S3 lineup; it distinguishes itself with a display that boasts brighter colours and higher contrast than the typical TFT screens.

The T4-S3 is part of LILYGO's continued efforts to integrate AMOLED technology into their products, following the T-Track and T-Display-S3 AMOLED boards. However, the T4-S3 sets a new standard with its larger screen size, touchscreen functionality, and aspect ratio, broadening its potential for various Human-Machine Interface (HMI) applications.
