Get a beta invite to Adafruit.io WipperSnapper
Wippersnapper is a new no-code IoT interface for Adafruit.IO – it lets you turn any WiFi-capable board into an IoT device without any programming. Simply select what devices are connected to which pins on the hardware and it will auto-configure the firmware and even create an IO feed for visualization.
How can I get an invite to the Adafruit.io WipperSnapper Beta?
First – You’ll need a compatible board to use with WipperSnapper. WipperSnapper currently supports the following hardware: Metro ESP32S2, FunHouse ESP32-S2, MagTag ESP32S2, PyPortal, Metro SAMD51+AirLift.
Then – Navigate to the official Adafruit Discord Server and post in #help-with-adafruit-io that you’d like a WipperSnapper beta invite. We’ll message you over Discord with further instructions!
