LilyGO TTGO T-Display-S3 AMOLED ESP32-S3 1.9 RM67162 WiFi Module

Product detailed description

LilyGO T-Display-S3 AMOLED is a compact development board featuring an ESP32-S3 chip and a 1.91" AMOLED display with a resolution of 240 × 536 pixels. Compared to the previous LCD version, it features a brighter AMOLED panel with an RM67162 driver and a high-speed QSPI interface, a 3D antenna, and integrated battery charging management. With 16 MB flash, 8 MB PSRAM, and low power consumption, it is ideal for wearables, small IoT terminals, or home control panels. The board can be programmed using Arduino IDE, PlatformIO, and MicroPython, and you can connect sensors without soldering via uSup connectors.

Note:

• This version of the board does not have a touch layer. The pinout diagram above is provided by the manufacturer and shows the version with touch – the pin layout is identical; pin IO21 serves as a user button here.
• Neither the battery nor the connection cables are included in the package.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
