3 x ESP32-C3 OLED WiFi Bluetooth Development Board with Expansion Shields, Screw & Non-Screw Terminals Lipo UPS Battery Charging for IoT Projects Compatible with Arduino IDE C++

Product Description Unlock endless possibilities in IoT, prototyping, and embedded projects with the Lonely Binary ESP32-C3 OLED Kit. This comprehensive bundle includes three high-performance ESP32-C3 development boards, each featuring a built-in OLED display for real-time data visualization and debugging. Paired with versatile expansion shields, this kit supports seamless integration of protected LiPo batteries (like 18650 cells) for portable, battery-powered applications. (Battery is not included.) Designed for uninterrupted operation, the LiPo battery functions like a UPS system: when Type-C is connected, the ESP32 draws power from it and charges the battery; if disconnected, the battery instantly takes over without rebooting or interrupting your code. The included shields provide flexible connectivity options: 2.54mm Expansion Shield with dual male/female GPIO pins to eliminate jumper cable mismatchesScrew Terminal Shield ideal for secure, permanent installationsNon-Screw Terminal Shield perfect for quick prototyping with raw cables All shields feature intelligent power management—stepping down battery voltage to a stable 3.3V for the ESP32-C3 while enabling simultaneous charging via USB Type-C. Plus, built-in battery monitor pads allow easy voltage monitoring by simply shorting them, ensuring you always know your power status. Compatible with Arduino IDE, C++, MicroPython, ESP-IDF, and more, this kit is designed for makers, hobbyists, and professionals building smart devices, sensors, or wearables. Whether you're creating a wireless display, battery-powered gadget, or custom prototype, the Lonely Binary ESP32-C3 OLED Kit delivers reliability, versatility, and ease of use in one affordable package. Bullet PointsTriple ESP32-C3 Boards with OLED Displays: Includes 3x compact ESP32-C3 development boards equipped with integrated OLED screens for instant data readout, Wi-Fi/Bluetooth LE connectivity —perfect for IoT prototyping and real-time monitoring.Lipo UPS Power Management: LiPo batteries (not included) act as an instant backup; Type-C powers the board and charges the battery when connected, switching to battery power without reboots or interruptions for continuous operation.Versatile Expansion Shields: Comes with a 2.54mm Expansion Shield featuring dual male/female GPIO pins to avoid jumper cable issues, a Screw Terminal Shield for durable permanent projects, and a Non-Screw Terminal Shield for fast prototyping with direct raw cable connections.Universal LiPo Battery Compatibility: All shields support any protected LiPo battery (e.g., 18650), with automatic 3.3V step-down for powering the ESP32-C3 and built-in charging via USB Type-C for uninterrupted operation.Battery Monitoring Made Simple: Integrated battery monitor pads on every shield—short them to enable real-time voltage tracking on your ESP32-C3, helping you manage power efficiently in portable setups.Ideal for Makers and Developers: Supports frameworks like Arduino, MicroPython, and ESP-IDF; great for wireless sensors, smart displays, or custom electronics—affordable, expandable, and user-friendly for beginners to experts.Package Includes3x Lonely Binary ESP32-C3 Development Boards with OLED Displays1x 2.54mm Expansion Shield with LiPo Battery Port1x Screw Terminal Shield with LiPo Battery Port1x Non-Screw Terminal Shield with LiPo Battery PortNote: LiPo batteries and jumper cables sold separately.
