Each board supports LiPo UPS power management with seamless battery backup via USB-C charging, ensuring uninterrupted operation. The kit includes three versatile expansion shields—2.54mm, screw terminal, and non-screw terminal—compatible with protected LiPo batteries for flexible prototyping and permanent installations. Ideal for makers and developers, it supports Arduino IDE, MicroPython, and ESP-IDF, empowering rapid creation of wireless sensors, smart displays, and custom electronics. ## Description Lonely Binary 3-Pack ESP32-C3 OLED Development Board Kit with Expansion ShieldsThe 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 Shields2.54mm Expansion Shield with dual male/female GPIO pins to reduce jumper cable mismatchesScrew Terminal Shield for secure, permanent installationsNon-Screw Terminal Shield for quick prototyping with raw cablesAll 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 Includes3 × Lonely Binary ESP32-C3 Development Boards with OLED Displays1 × 2.54mm Expansion Shield with LiPo Battery Port1 × Screw Terminal Shield with LiPo Battery Port1 × Non-Screw Terminal Shield with LiPo Battery PortNote: LiPo batteries and jumper cables sold separately.Designed in AustraliaLonely Binary is an independent Australian brand focused on open-source maker hardware. ## Features - 【TRIPLE ESP32-C3 BOARDS WITH OLED DISPLAYS】Includes 3 compact ESP32-C3 development boards with integrated OLED screens for data readout and Wi-Fi/Bluetooth LE connectivity — for IoT prototyping and real-time monitoring. - 【LIPO UPS POWER MANAGEMENT】LiPo batteries (not included) act as 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 (dual male/female GPIO pins), a Screw Terminal Shield for permanent projects, and a Non-Screw Terminal Shield for fast prototyping with direct cable connections. - 【UNIVERSAL LIPO BATTERY COMPATIBILITY】All shields support protected LiPo batteries (e.g., 18650), with automatic 3.3V step-down for the ESP32-C3 and charging via USB Type-C for uninterrupted operation. - 【BATTERY MONITORING MADE SIMPLE】Integrated battery monitor pads on every shield — short them to enable voltage tracking on your ESP32-C3 for power management in portable setups. - 【FOR MAKERS AND DEVELOPERS】Supports Arduino IDE, MicroPython, and ESP-IDF — suitable for wireless sensors, smart displays, and custom electronics for beginners to experienced makers. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0G6YT4ZQ3 | | Best Sellers Rank | #1,761 in Single Board Computers (Computers & Accessories) | | Brand | LONELY BINARY | | Built-In Media | 1x 2.54mm Expansion Shield with LiPo Battery Port, 1x Non-Screw Terminal Shield with LiPo Battery Port, 1x Screw Terminal Shield with LiPo Battery Port, 3x Lonely Binary ESP32-C3 Development Boards with OLED Displays, Note: LiPo batteries and jumper cables sold separately. | | CPU Model | E-Series | | Compatible Devices | Arduino UNO Arduino Mega Arduino Nano, ESP32 Development Boards Raspberry Pi 3 / 4 / 5, Raspberry Pi Pico STM32 Microcontrollers Other 3.3V / 5V Microcontroller Boards | | Connectivity Technology | Bluetooth, Wi-Fi | | Customer Reviews | 4.6 4.6 out of 5 stars (26) | | Manufacturer | Lonely Binary | | Memory Storage Capacity | 4 MB | | Mfr Part Number | 3-PACK ESP32-C3 OLED Kit | | Model Name | 3-PACK ESP32-C3 OLED Kit | | Model Number | 3-PACK ESP32-C3 OLED Kit | | Operating System | Arduino IDE | | Processor Brand | Espressif | | Processor Count | 3 | | RAM Memory Technology | LPDDR2 | | Smart Home Compatibility | Not Smart Home Compatible | | Total Usb Ports | 1 | | Unit Count | 6.0 Count | | Warranty Description | 1 Year Warranty | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** LONELY BINARY - **CPU Model:** E-Series - **Connectivity Technology:** Bluetooth, Wi-Fi - **Memory Storage Capacity:** 4 MB - **Model Name:** 3-PACK ESP32-C3 OLED Kit ## Images ![Lonely Binary 3-Pack ESP32-C3 OLED WiFi BLE LiPo Shield for Arduino IDE | Built-in OLED, WiFi + BT 5.0 LE; 3 shields: 2.54mm, screw & non-screw terminal; LiPo UPS charging, 3.3V; battery monitor pads - Image 1](https://m.media-amazon.com/images/I/81LQd06CrUL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/802157605-lonely-binary-3-pack-esp32-c3-oled-wifi-ble-lipo](https://www.desertcart.ro/products/802157605-lonely-binary-3-pack-esp32-c3-oled-wifi-ble-lipo) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-11*
