SERCOM (Serial Communication) is a multiplexed serial configuration used on the SAMD21, SAMD51 and other boards. It allows you to select various serial functions for most of your pins.

The Qwiic RFID ID-XXLA is an I2C solution that pairs with the ID-LA modules: ID-3LA, the ID-12LA, or the ID-20LA, and utilizes 125kHz RFID chips. Using the product's interrupt pin, we'll discuss how to get, store, and compare unique RFID IDs.

In this tutorial, we'll discuss how the time is set with the on board six DIP switch and use a microcontroller to turn it off when a task is finished.

In this hookup guide, we'll connect our sensor up to our Esp32 Thing Plus microcontroller and run a of quick (Qwiic) example to get you up and running with this fantastic board!

The SparkFun Pi Servo pHAT provides your Raspberry Pi with 16 PWM channels that can be controlled over I2C. These channels are broken out in a header combination that is perfect for connecting servo motors.

The PCA9306 is a dual bi-directional voltage translator for the I2C-bus and SMBus. It works at a range of voltages between 1.2V and 5.0V and doesn't require a direction pin to function. This is a great board for shifting voltages between sensors and your microcontroller.
