Placeholder Pimoroni Breakout Garden for Raspberry Pi 400 –

Pimoroni Breakout Garden for Raspberry Pi 400


Now at right angles for the Raspberry Pi 400! An easy, solderless, swappable way to use breakouts with your Raspberry Pi 400 - just pop up to three Pimoroni breakouts (2 x I2C, 1 x SPI) into the slots and get coding and creating!

Breakout Garden plugs into your shiny new Pi 400's GPIO pins and lets you connect up to three of our extensive selection of Pimoroni breakouts so they're conveniently facing towards you and the right way up. Pimoroni has environmental sensors so you can keep track of the temperature and humidity in your office, a whole host of little screens for important notifications, readouts and GIFs, and, of course, LEDs.

The three sturdy black slots are edge connectors that connect the breakouts to the pins on your Raspberry Pi. There's one slot for SPI breakouts and two for I2C breakouts. Because I2C is a bus, you can use multiple I2C devices at the same time, providing they don't have the same I2C address (we've made sure that all of our breakouts have different addresses, and we print them on the back of the breakouts so they're easy to find).

As well as being a handy way to add functionality to your Pi 400, Breakout Garden is also very useful for prototyping projects without the need for complicated wiring, soldering, or breadboards, and you can grow or change up your setup at any time.

Please note that breakouts are sold separately!

Using Breakout Garden

Because of the way that I2C (the protocol that Breakout Garden uses) works, it doesn't matter which slot on the Breakout Garden that you plug your 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 SPI slot on Breakout Garden Mini uses chip select 1 (BCM 7) and BCM 19 for the GPIO pin (used for things like LCD backlights).

Pimoroni built reverse polarity protection into the 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 400 slot match up.

We've also broken out a load of useful pins along the top of Breakout Garden Mini, so you can connect other devices and integrate them into your Breakout Garden projects. If you have Pimoroni breakouts to which you've already soldered headers, then you can use this top row of pins to use them alongside other breakouts on Breakout Garden Mini.

This allows you to have an easy access to the pin outs of the GPIO and connections for for other cards and/or experiments ect. I have yet to be sorry from ordering from Vilros
