Description:

Game On! These wireless games controllers are perfect for all of your Raspberry Pi gaming or robotics needs.

Please note: These are not Bluetooth controllers - they're 2.4GHz wireless (and come with the USB receiver).

Gaming

Compatible with RetroPie/Lakka - simply plug in the controller at boot and follow the controller setup instructions.

You may need to configure buttons for the specific emulator/game you're playing. The RetroPie/Lakka websites and forums are a great place to find out more on button assignments.

For analogue control, make sure you press the analogue button on the controller to enable full analogue thumbstick action (otherwise this is seen as simple button clicks)

Robotics

Control your Raspberry Pi robots with ease! We've got instructions for using these controllers with the CamJam EduKit 3 (although other driver boards and kit will work too)

You can also use the excellent Approximate Engineering Input library!

Install the library by using the following commands:

sudo apt-get install python-dev python-pip gcc

pip3 install approxeng.input

Please run your script with Python 3 when using this library! (Python 2 may not work).

Description:

This minimal Camera for the Pi Zero is perfect for small camera projects where space is at a premium.

The sensor is 5MP, and the whole shebang is mounted on a flexible circuit board. As such, a little care is needed when handling, just like the connector on the Pi Zero. Easy there Lennie.

Otherwise it's an economical and svelte solution for birdcams, bodycams, home security and simple computer vision projects.

Update: Without an IR filter, which is useful for night vision, especially when using IR lights to illuminate the subject

Only for Raspberry Pi Zero with CSI camera port.

Approx dimensions of camera: 10mm x 11.4mm x 5.1mm
