The Great Search: Triple-Axis Magnetometer replacement for LIS3MDL #TheGreatSearch @digikey @adafruit
(Video) One part that’s been holding up a lot of Adafruit’s products from staying in stock is the LIS3MDL. Originally this was a $1 triple-axis magnetometer that paired well with IMU chips for making full-fusion orientation sensors. Now they’re going for $20 on the gray market with an estimated ship date of 2059 (e.g. ‘who knows’).
Since we were out of IMU chips for a while, we were OK waiting. But now we’ve got some in stock and with no magnetometer shortage end in sight, we’re thinking of just replacing the LIS3MDL. Especially since the magnetometer is not the most sensitive sensor in a 9-DoF (that would be the gyro). Let’s identify a sensor with about +-20 gauss (+-2 mT) range, I2C interface, and affordable enough so we don’t have to change our prices.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
