To calibrate the outputs, the user must issue a command to set the output to a desired value, measure the result and issue the calibration command to store the value.

We've got 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 Pi 500 is great, but needs more LEDs, amirite?). We've got a ton more too - check out the complete list of breakouts here!\u003c\/p\u003e\n\u003cp\u003eThe 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 (like our 0.96\" LCD Breakout or 1.12\" SPI OLED Breakout), 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).\u003c\/p\u003e\n\u003cp\u003eAs well as being a handy way to add functionality to your Pi 500, 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBreakouts are sold separately! \u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003eCheck out our full range of Breakout Garden's and Breakout's \u003c\/span\u003ehere!\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with Raspberry Pi 500 and 400\u003c\/li\u003e\n\u003cli\u003eThree sturdy edge-connector slots for Pimoroni breakouts\u003c\/li\u003e\n\u003cli\u003e2x I2C slots (5 pins)\u003c\/li\u003e\n\u003cli\u003e1x SPI slot (7 pins)\u003c\/li\u003e\n\u003cli\u003e0.1” pitch, 5 or 7-pin connectors\u003c\/li\u003e\n\u003cli\u003eBroken-out pins\u003c\/li\u003e\n\u003cli\u003eReverse polarity protection (built into breakouts)\u003c\/li\u003e\n\u003cli\u003eExclusive right angle format for the Pi 400\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eUsing Breakout Garden\u003c\/h2\u003e\n\u003cp\u003eBecause of the way that I2C (the protocol that Breakout Garden uses) works, it doesn't matter which slot on the Breakout Garden 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!\"\u003c\/p\u003e\n\u003cp\u003eSPI is a faster, higher-throughput protocol for talking to devices like displays.
