Particle | Electron 3G Device | Internet of Things (IoT) Board | All-in-One Development Kit | Free Cloud Access | PCB & SIM Card | Create Cellular Connect Products | Great for Electronics Projects POWERFUL INTERNET OF THINGS DEVICE: This tiny development kit was designed specifically for creating cellular-connected electronics projects. It includes embedded security from hardware to cloud and access to Particles Device Cloud platform. DEVICE CLOUD ACCESS: All Particle hardware is designed from the ground up to work with the Device Cloud, plus your first three months of cellular data is free. The Device Cloud is a powerful set of tools and infrastructure to build, connect, and manage your IoT fleet. It includes over-the-air firmware updates, connectivity management, and remote diagnostics. GLOBAL CELLULAR CONNECTIVITY: Particles Electron 3G has you covered in more than 100 countries worldwide. The Electron itself is a GSM-only device, does not support CDMA, and will work directly in North America, South America, and Australia out of the box. The kit also includes a Particle SIM that covers 100 countries. The Device Cloud includes 3MB of cellular data per device/per month and your first three months of data is FREE. SPECS & FEATURES: Connect in minutes out of the box and build in the Arduino-compatible language C+ Particles Electron Kit includes a microcontroller, SIM card, cellular antenna, li-po battery, printed circuit board (PCB), USB cable, breadboard and a pinout reference card. 1MB flash and 128K RAM with a u-blox cellular modem. UNLOCK ACCESS TO CELLULAR IOT: Particle makes the access to cellular connectivity incredibly easy so you can jump directly to building your Iot application without negotiating carrier rates, setting up a cloud infrastructure, coding low-level firmware, or creating your own device management tools. The Particle Electron Kit has everything you need to prototype your IoT project and bring physical objects online.
