ESP32-S3-Touch-AMOLED-2.16 specifications: Wireless MCU – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration. Memory – 512KB RAM, 8MB PSRAM ROM – 384KB Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE Storage 16MB NOR flash MicroSD card slot […]
