What is a Qwiic connector?
Qwiic is SparkFun's proprietary ecosystem that includes numerous sensors based on the I2C bus , executive modules and dedicated cables . The main assumption of this solution is to streamline the prototyping process. All components supporting the Qwiic standard use a common, 4-pin JST connector with a pitch of 1 mm , which reduces the amount of space required on the printed circuit board, and also protects against connecting the power supply in accordance with the polarity.
What is an accelerometer? What does it do?
An accelerometer, alternatively known as an accelerometer , is a sensor that allows you to determine acceleration (in three axes). An accelerometer is a kind of transducer that measures linear acceleration, i.e. it measures its own motion. Wondering where exactly the accelerometer is used? You will even find it in your smartphone, because it is thanks to it that the device counts the steps you take. You can learn more about the accelerometer from the article available on our blog - welcome!
