SparkFun Micro Magnetometer - MMC5983MA (Qwiic)

by Sparkfun

The SparkFun Qwiic Micro MMC5983MA Magnetometer is a micro-sized, 0.75in. by 0.30in. sensor that utilizes the highly sensitive triple-axis magnetometer by MEMSIC.

SparkFun have attached the magnetometer IC onto an incredibly small Qwiic board form factor that they like to call Qwiic Micro! The MMC5983MA is capable of sensing down to 0.4mG, enabling a heading accuracy of ±0.5°. The Qwiic MMC5983MA IMU communicates over I2C by default utilizing the handy Qwiic Connect System, so no soldering is required to connect it to the rest of your boards.

Saturation is a problem for all mag sensors. The MMC5983MA has built-in degaussing circuitry to clear any residual magnetization. Output rates of 1000Hz, ±8G FSR, and 18-bit resolution make the MMC5983MA a phenomenal magnetic sensor for electronic compass applications.

SparkFun have also written a feature complete Arduino library supporting I2C and SPI. Just search "SparkFun MMA5983MA" in the library manager and start measuring within minutes.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Qwiic Micro is the smallest I2C-supported board form-factor yet! At only 0.75in. by 0.30in. (or 24.65mm by 7.62mm for metric friends), Qwiic Micro is perfect for projects and applications that have space or weight concerns. With just a single Qwiic connector, Micro boards work great alongside the Qwiic Multiport or at the end of a Qwiic daisy chain.

Another day another Pi project, this time a Pi4b as it can use the SMI bus (not available on the Pi5 due to the custom interface chip driving the GPIO). Fitted to a Uctronics Pi Rack SSD carrier with a 256G SSD via a USB3 adapter and Caribou Lite SDR.

I needed an economical replacement for an old Pi B+ that was running out of oomph for the application I was using it for. A 1Gb Pi 4b fills the bill nicely at a very reasonable price. ... and it really is a **lot** faster! :-)

Great product from pimoroni. I have used it for a mobile robotic cart, a fixed robotic arm, network attached storage, 3d print monitoring & control. I bought this pi4b with 2gb for a mini Observatory called pilomar on instructables.

Came quickly and works as expected. Played around with the Breakout garden to test a few sensors, all working straight away. Would definitely buy again

Amazing piece of kit. I upgraded from a Pi 3B so I could play more stuff on Batocera. It plays everything you can throw at it.

I wanted to upgrade by Home Assistant configuration as it was running slowly on a PI 3. A pi 5 was overkill but the pi 4 model b is ideal for current and future home automation.

The Raspberry Pi is an excellent platform for a wide variety of uses. A full-blown ARM Linux system with a wide array of GPIO and other capabilities (SPI, CAN, I2C, etc.). Easy development tools readily available and lots of onine help for a wide variety of tasks. A great introductory platform for those just starting out and a great SOC platform for those looking to do more advanced microcontroller tasks.

I had purchased this to use for octoprint to control my Creality 3d printer. As expected it met all my needs and is very useful in controlling and printing. I have 3d printed a shell and added a fan to ensure it is always cool.

Absolutely delighted with the fast delivery and everything was up and running withing 20 minutes when i received my Pi (Now controlling my 3D printers). Could not fault any part of the process dealing with Pimoroni!

Wonderful device, and has replaced a fairly hefty and expensive Intel NUC running Homeassistant. As for Pimoroni, everything went smoothly, from purchase to delivery :-)

This is my second Pi4, this time a 2GB because I was using it for an OctoPi setup for my 3D printer. It's a great bit of kit. Pimoroni were great (and I'm proud to support a company just up the road). Good value, fast delivery. Got Octopi/octoprint set-up in minutes and was away. My other one is set-up with Home Assistant et al. Really powerful little board that opens up a world of possibilities for managing your house or just fun projects.

I have several RPi 4B's in service and can say with confidence, the extra RAM does increase performance dramatically. Glad they are becoming available again.

My Pi arrived the next day and I was quickly up and running. I’m using it to run various Docker containers headlessly, so I haven’t tested out the HDMI capabilities. Top tip, if you use the official Raspberry Pi Imager software you can preconfigure your Wi-Fi settings and SSH key information. That means you just apply power and the Pi is immediately on the network and SSH access works out of the box.

Product itself as expected - excellent. What was over and above was the after sales customer support. I had an issue with the RPI and a new one was shipped out FOC and a free return (Royal Mail pickup) was arranged. So easy thank you.

what you see is what you get, warms up a bit but doesn't get dangerously (for itself or myself) hot

It's great these are finally back in stock - they are a brilliant and versatile little mini computer - great for a variety of software and hardware projects or even just for use as a general computer as they have plenty of power. You can never have enough because you will keep coming up with new ways of using them and on that note I will be buying more - just waiting for the 8GB model to come back in stock.

Finally we have them back. These boards are the core for some projects that can only use the power that we get from the Raspberry Pi 4 B 4GB.

Brilliant little computer that is perfect for so many computer projects. In my case it was paired with an Argon One m.2 case and used as a Plex media server. The extra RAM and processing power of the Pi 4 8GB model is a substantial improvement over the Pi 3 and well worth the upgrade. Overall I'm very happy with my purchase, but don't just take my word for it, buy one and find out for yourself.

With 8GB this Pi4 is far better able to cope with being used as a Desktop Computer and when running memory hungry applications than my older 4GB model was. Reasonable price and everything seems to be working fine.

This is my first 8 GB model, on which I installed the 64-bit Raspberry Pi OS. I have several 4 GB boards which do several jobs on my home network. They're speedy and reliable. I also note that they run Rocky Linux 9 very well, too.
