Lonely Binary ESP32 LiPo Charger Development Kit Elevate your IoT, prototyping, and embedded electronics projects with the Lonely Binary ESP32 LiPo Development Kit. This all-in-one bundle features three robust ESP32 development boards, each equipped with a built-in LiPo battery charger for seamless integration of protected LiPo batteries (like 18650 cells, not included). Connect a LiPo battery directly to the board for portable power, with the USB Type-C port enabling simultaneous charging while in use.
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 kit includes versatile shields with power switches for added control:
2.54mm Expansion Shield with dual male/female GPIO pins to prevent jumper mismatches
Screw Terminal Shield for secure permanent setups
Non-Screw Terminal Shield for rapid prototyping with raw cables
All shields feature battery connections, on/off switches, and voltage monitor pads (short them for real-time battery level tracking on the ESP32).
Powered by the Espressif ESP32 chip, these boards offer dual-core processing, 4MB Flash, Wi-Fi, and Bluetooth for versatile connectivity. Compatible with Arduino IDE, ESP-IDF, C++, MicroPython, and more, this kit is perfect for makers, engineers, and hobbyists building wireless devices, sensors, or battery-backed systems that demand reliability and flexibility.
Triple ESP32 Boards with Built-in LiPo Chargers: Includes 3x Lonely Binary ESP32 development boards featuring integrated LiPo chargers (max 500mA), 4MB Flash, dual-core processing, Wi-Fi/Bluetooth connectivity—ideal for portable IoT applications and seamless battery integration.
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 with Power Switches: Comes with a 2.54mm Expansion Shield offering dual male/female GPIO pins for hassle-free connections, a Screw Terminal Shield for durable permanent projects, and a Non-Screw Terminal Shield for quick prototyping with direct raw cables.
Battery Connectivity and Control on Shields: All shields include LiPo battery ports, built-in power switches for on/off control, and voltage monitor pads—short them to enable real-time battery level monitoring on your ESP32.
Broad Compatibility for Developers: Supports frameworks like Arduino, MicroPython, and ESP-IDF; perfect for wireless sensors, smart gadgets, or custom prototypes—reliable, expandable, and user-friendly for beginners and experts alike.
