Introduction
The T-Display-S3 AMOLED 1.64 is a high-performance IoT development board built around the ESP32-S3R8 dual-core LX7 microprocessor, featuring integrated 2.4 GHz Wi-Fi and Bluetooth 5 (LE) connectivity. It supports multi-platform development, including Arduino, PlatformIO IDE, and ESP-IDF.
Its standout feature is the 1.64-inch ICMA3311 AMOLED display with a resolution of 280×456 pixels, connected via a QSPI bus interface and compatible with the Arduino_GFX graphics library, enabling rapid development of rich graphical user interfaces.
The board comes with 16MB Flash and 8MB PSRAM, providing ample storage and memory resources. It also supports battery voltage detection (via ADC pin I004) and 5V/500mA USB charging, balancing low power consumption with mobile application needs.
Additional features include capacitive touch input, explicit hardware flow control, STEMMA QT/Qwiic expansion interface, and RF SH 1.0mm + 4W RF design, making it ideal for use in smart wearables, embedded GUI applications, and industrial control. Its compact 28×42mm form factor delivers a strong balance of performance and functionality.

Attention
If users need to adjust the external antenna resistance, please refer to the following.
The resistor jumper section is obscured by hardware in the image. You can refer to the method described in the T3-S3 LR1121 documentation to adjust the resistor orientation and thereby modify the resistance of the external antenna.
