The Beetle ESP32 Microcontroller from DFRobot is a miniaturized, feature-rich development board built around the Espressif ESP32 system-on-chip. It provides a complete wireless IoT solution in a footprint significantly smaller than standard ESP32 dev boards, making it ideal for embedding into final products, wearables, or compact sensor modules. The board includes gold-plated, honeycomb-style power and I/O connectors designed for screw-terminal wiring or conductive thread sewing, facilitating rapid prototyping without soldering.
It supports a wide input voltage range, allowing flexible power sourcing from a USB port (5V) or an external DC supply (3.5-6.5V). The integrated wireless stack supports common WiFi protocols and Bluetooth Low Energy, enabling local network communication and device pairing. With its direct program upload via Micro USB and comprehensive peripheral set, the Beetle ESP32 serves as a high-performance, low-profile core for building connected sensor systems and interactive electronic projects.
