  • Using Breakout Garden

  • We'd suggest using the included standoffs to attach Breakout Garden firmly to your Raspberry Pi. Pop the screws through the mounting holes on your Raspberry Pi, from below, and then screw the standoffs onto the screws. Push Breakout Garden onto your Pi's GPIO pins, and then screw through each mounting hole into the standoffs to hold everything steady and secure.

    Because of the way that I2C (the protocol that Breakout Garden uses) works, it doesn't matter which slot on Breakout Garden you plug your Pimoroni breakout into. Each I2C device has an address (you'll see it on the back of each breakout) that it uses to identify itself to other I2C devices, so it's effectively saying to your Raspberry Pi, "Hey, it's me, Bob!"

    SPI is a faster, higher-throughput protocol for talking to devices like displays. The two SPI slots have different chip select (CS) and GPIO pins that you should change in software, depending on which slot you're using.

    The top/back slot (closest to the Breakout Garden logo) uses chip select 0 (BCM 8) and BCM 18 for the GPIO (used for things like LCD backlights) pin. The bottom/front slot uses chip select 1 (BCM 7) and BCM 19 for the GPIO pin.

    We've built reverse polarity protection into our Pimoroni breakouts, meaning that there's no magic blue smoke if you accidentally plug one in the wrong way round. However, the correct way to plug them in is to make sure that the labels on the pins on your breakout and the labels on each Breakout Garden slot match up.

    Software

    Head over to the Breakout Garden GitHub repo and give our automagic installer a go. Just pop a few breakouts into Breakout Garden, run the installer, and SHAZAM!, the software for the appropriate breakouts will be installed (this won't work for SPI breakouts). We've also got a few nice examples to show you what's possible.
