Lonely Binary 3X ESP32 LiPo Charger WiFi Bluetooth Development Board with 3 x Expansion Shields, Screw & Non-Screw Terminals, Power Switches & Lipo UPS Battery Support for IoT Projects

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 mismatchesScrew Terminal Shield for secure permanent setupsNon-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.Package Includes:3x Lonely Binary ESP32 Development Boards with LiPo Chargers1x 2.54mm Expansion Shield with Power Switch1x Screw Terminal Shield with Power Switch1x Non-Screw Terminal Shield with Power Switch1x Type-C to USB CableNote: LiPo batteries and jumper cables sold separately.
