GPIO modules

this page showcases hardware modules that can be created for flipper one and connected via the gpio port two modules are currently documented the walkie talkie module and the camera module walkie talkie module this module enables communication over standard vhf frequencies with walkie talkies using the flipper one microphone, speaker, and ptt button it is built around an sa828 based walkie talkie radio module walkie talkie module structural diagram the module connects to flipper one via the gpio header's usb 2 0 pins (d+, d , 5v, gnd) and carries microphone audio, speaker audio, and a ptt control signal between flipper one and the radio rf transmission and reception go through an external antenna attached to the sa828 module camera module this module turns flipper one into a point and shoot camera for capturing pixel art images, with a live preview rendered on the built in screen at 256 × 144 pixels and 64 greyscale levels camera module structural diagram flipper one's linux os recognizes the module as a standard usb webcam, making it available for taking pictures and recording videos the camera module is based on a typical usb webcam, connecting via the usb 2 0 pins (d+, d , gnd) and powered through the 5v output pin on the gpio header
