ESP32-S3 1.91-inch AMOLED Board with ESP32-S3R8, RM67162 Driver, and FT3168 Touch Controller

The ESP32-S3 1.91-inch AMOLED development board is designed for rapid prototyping of IoT and portable applications. Powered by the ESP32-S3R8 chip with a 240 MHz dual-core processor, it supports 2.4 GHz Wi-Fi and Bluetooth BLE 5, 16 MB Flash, and 8 MB PSRAM. Its capabilities are further enhanced by a 6-axis motion sensor, making it ideal for interactive and motion-responsive projects.

The board’s 1.91-inch AMOLED display boasts a 240×536 resolution with 16.7 million colors and is driven by the RM67162 controller via QSPI. Available in both touch and non-touch versions, the touch models use the FT3168 IC for precise input detection. Additional features include a QMI8658 6-axis IMU, a microSD card slot, and a Lithium battery header, providing flexibility for a wide range of applications.

Previously, we covered several ESP32-S3R8 development boards with displays, including the LILYGO T-Display S3 AMOLED, LILYGO T3S3 E-Paper, Banana Pi BPI-Centi-S3, and LILYGO T-Embed. If you’re interested, feel free to explore these products.
