Flipper Zero Mayhem Hat Adds Camera, More Radios - Hackaday

But some hard decisions had to be made to get the retail price down, so features like WiFi and Bluetooth had to be left off.

Luckily, there’s an expansion interface along the top of the device which makes it possible to plug in additional hardware.

The addition of an ESP32-CAM brings WiFi and Bluetooth to the party, while also unlocking access to the highly-capable ESP32Marauder firmware and the plethora of security research tools therein.

But the camera also enables some interesting features, such as motion detection and the ability to read QR codes.

There’s a spot to plug in either a CC1101 or NRF24l01 radio module, both of which are supported by community developed plugins that allow the user to sniff out and hijack signals.

In the demo video below you can see the device automatically detect the popular DHT11 environmental sensor and display the current temperature and humidity readings.
