Build projects that can transmit and receive data from just about anywhere using cellular data! Unlike transports that require a router, wires, or a gateway, cellular towers are located just about anywhere people are.
We designed a CircuitPython library compatible with the Adafruit FONA SIM808/SIM800 cellular modem. This module handles all the complicated modem interfacing for you, so you can bring your IoT projects online quickly.
In this guide, you will set up and configure a FONA module with a CircuitPython board to connect to the internet over a cellular network. We’ve included examples for using this module to send HTTP requests and connect to MQTT brokers.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
