Lonely Binary 3-Pack ESP32-C3 OLED Development Board Kit with Expansion Shields
The Lonely Binary ESP32-C3 OLED Kit includes three ESP32-C3 development boards, each with a built-in OLED display for real-time data visualization and debugging. Paired with expansion shields, the kit supports protected LiPo batteries (such as 18650 cells) for portable, battery-powered applications. (Battery not included.)
The LiPo battery functions like a UPS: when Type-C is connected, the ESP32 draws power from it and charges the battery; if disconnected, the battery takes over without rebooting or interrupting your code.
Included Shields
- 2.54mm Expansion Shield with dual male/female GPIO pins to reduce jumper cable mismatches
- Screw Terminal Shield for secure, permanent installations
- Non-Screw Terminal Shield for quick prototyping with raw cables
All shields step down battery voltage to a stable 3.3V for the ESP32-C3 while enabling simultaneous charging via USB Type-C. Built-in battery monitor pads allow voltage monitoring by shorting them.
Compatible with Arduino IDE, C++, MicroPython, ESP-IDF, and more suitable for makers, hobbyists, and professionals building smart devices, sensors, or wearables.
Package Includes
- 3 × Lonely Binary ESP32-C3 Development Boards with OLED Displays
- 1 × 2.54mm Expansion Shield with LiPo Battery Port
- 1 × Screw Terminal Shield with LiPo Battery Port
- 1 × Non-Screw Terminal Shield with LiPo Battery Port
Note: LiPo batteries and jumper cables sold separately.
