ESP32-S3-N16R8

About this product

Yahboom ESP32-S3-N16R8 is a core board for AI voice interfaces, robotics education and embedded development. It integrates an Espressif ESP32-S3 module with dual-core Xtensa LX7 processing, 16 MB Flash and 8 MB PSRAM. The board adds a microphone, speaker connector, two Type-C connections, buttons and programmable RGB indication. Wi-Fi and Bluetooth LE functions, firmware methods and mode-specific current figures are detailed in Specifications. An external speaker and OLED display belong to optional bundles. Access to cloud language models is a software/network capability, not a claim that the board runs a large model locally.
