The SparkFun Qwiic Speaker Amp includes the Texas Instruments TPA2016D2 stereo, filter-free class-D audio power amplifier. What distinguishes this audio amplifier from others is that it features volume control (i.e. gain), Dynamic Range Compression (DRC), Automatic Gain Control (AGC), enable/disable amplifier, and its ability to be configured through software via I2C. Its efficient class-D operation also means low heat and long battery life when driving 4Ω speakers at up to 2.8W in stereo, and...

QR codes are a great way for users to communicate with microcontrollers, whether it’s passing WiFi credentials to set up connectivity or sending personal information to fill out a digital badge. Reading them from a maker project didn’t used to be easy though. You’d either needed a large and relatively expensive standalone module, or your own software solution on a board with a camera. The Tiny Code Reader from Useful Sensors is smaller than a quarter, very low cost, and connects through Qwiic....
