FireBeetle 2 ESP32-S3 (N4) IoT Microcontroller (No Cam, 4MB Fl., AI Accel.)
Dual-core ESP32-S3 board with 4 MB flash, 512 KB SRAM, Wi-Fi, Bluetooth 5, and AI vector acceleration. No camera connector; choose this over N16R8 variants when camera support is not needed and cost or size is a priority.
ESP32
110 other optionsWi-Fi and Bluetooth on a single chip, in every shape from Espressif DevKitC to Adafruit Feathers with STEMMA QT, DFRobot FireBeetles tuned for battery life, and Seeed XIAOs under a thumbnail.
