ESP32-S3 AMOLED touch 2.16" 480x480 - Waveshare 33970

Description

Development board based on the ESP32-S3R8 chip with a dual-core Xtensa LX7 processor operating at up to 240 MHz. The system provides 512 kB SRAM, 384 kB ROM, 8 MB PSRAM and 16 MB Flash memory, enabling advanced IoT applications, communication systems and user interfaces.

The board integrates a 2.16" AMOLED display with 480 x 480 px resolution and 16.7M colors, equipped with a capacitive touch panel. AMOLED technology provides high contrast, wide viewing angles and fast response time. The display is driven via QSPI interface with CO5300 controller, while the touch panel uses the CST9220 chip.

The design also includes a 6-axis IMU module, RTC, audio codec and dual microphones with noise reduction and echo cancellation, enabling voice recognition systems and interactive applications. The MX1.25 connector allows connection of a 3.7 V Li-Ion battery (not included) with charging and power management handled by the AXP2101 chip.

Wireless connectivity includes 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 LE. Programming is performed via USB Type-C port, with support for ESP-IDF and Arduino environments.
