Product Description
Start IoT and wearables development with the ultra-compact NULA Mini ESP32-C6, featuring WiFi 6, Bluetooth 5.3, and Thread/Zigbee connectivity in a breadboard-compatible 25.33×25.33mm form factor. Built around Espressif’s powerful ESP32-C6-MINI-1-N4 module with dual RISC-V cores (160MHz high-performance + 20MHz low-power), this board delivers wireless capabilities with power efficiency. Perfect for smart home nodes, IoT sensors, and battery-powered devices requiring wireless protocols, this board combines the latest connectivity standards with maker-friendly features like Qwiic connectors and Arduino, MicroPython and ESP-IDF support.
Engineered for both prototyping and production deployment, the NULA Mini features 512KB high-performance SRAM, 4MB Flash memory, and 6 versatile GPIO pins supporting UART, SPI, I2C, PWM, and 12-bit ADC functions. Due to its small footprint, it’s very convenient for breadboard prototyping. The integrated Qwiic/STEMMA QT connector enables tool-free sensor integration, while the JST battery connector with onboard power management supports 3.7V Li-Ion batteries for portable applications. Ultra-low power consumption with hardware security features, including secure boot, flash encryption, and hardware crypto engines makes this ideal for professional IoT deployments requiring both performance and security.
This board represents the perfect balance of advanced wireless capabilities and maker accessibility, supporting WiFi 6 efficiency, Bluetooth mesh networking, and Thread/Matter compatibility for future-proof IoT projects. The breadboard-compatible design with bottom-mounted ESP32-C6 maximizes prototyping space while LEGO-compatible mounting holes enable secure project integration. Complete open-source hardware design with documentation ensures unlimited customization possibilities for both hobbyist and professional applications.
