SparkFun ESP32 Thing Motion Shield

The SparkFun ESP32 Thing Motion Shield is a versatile, motion-sensing addition to our ESP32 Thing. With the Motion Shield’s onboard LSM9DS1 IMU, small movement changes can easily be detected, while larger movements and time traveled can be detected with the addition of a GPS module via a large JST port. In addition, we have added breakout pins to attach any serial device, as well as a microSD card slot to log all of your data. All you need to do is solder on headers, and your ESP32 Thing Motion Shield will be ready to detect any type of movement!

The LSM9DS1 is one of only a handful of ICs that can measure three key properties of movement — angular velocity, acceleration and heading — in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an object’s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/z, angular rotation in x/y/z and magnetic force in x/y/z.

Each sensor in the LSM9DS1 onboard the Thing Motion Shield supports a wide spectrum of ranges: the accelerometer’s scale can be set to ± 2, 4, 8 or 16 g; the gyroscope supports ± 245, 500 and 2000 °/s; and the magnetometer has full-scale ranges of ± 4, 8, 12 or 16 gauss.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
