Adafruit 16×9 Charlieplexed PWM LED Matrix Driver – IS31FL3731 – STEMMA QT / Qwiic: To get you going fast, we spun up a custom-made PCB in the STEMMA QT form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the IS31FL3731 or to chain it with a wide range of other sensors and accessories using a compatible cable. The IS31 is compatible with 3-5V power and logic, so it’s ready to go with just about any microcontroller or microcomputer board!
ChronoDot – Ultra-precise Real Time Clock – v3: The ChronoDot V3 is the latest version of macetech’s popular ChronoDot line of products. Designed during the Great Chip Shortage, it uses the newly-released MAX31328 temperature-compensated real-time clock chip. However, it remains pin- and code-compatible with the older DS3231-based ChronoDots, and has the same clock accuracy and drift specifications. The MAX31328 chip is also in a smaller package, which allowed a few additional enhancements to the design.
Adafruit PCA9546 4-Channel I2C Multiplexer – TCA9546A Compatible: You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize “Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins!” Are you out of luck? You would be if you didn’t have this ultra-cool PCA9546 1-to-4 I2C multiplexer!
Adafruit PCA9546 4-Channel STEMMA QT / Qwiic I2C Multiplexer – TCA9546A Compatible: In case you’re wondering why this uses the PCA9546 and not the TCA9546A, the PCA9546 is the ‘fraternal twin sister’ of the TCA9546 but is easier to get during the great chip shortage of 2022. It works exactly the same, just can’t go down to 1.8V power which is OK because QT boards are 3V or 5V only anyways. You can still use any example code or library for the TCA9546 or TCA9548
Adafruit QT 3V to 5V Level Booster Breakout – STEMMA QT / Qwiic: If you’re looking to use the Qwiic / Stemma QT standard for your next project – but you’re using a sensor or device that requires 5V power or logic, this board is designed for you! It will let you use the 3V power and logic from your Raspberry Pi, or ARM Cortex microcontroller, and boost/shift it up to 5V for use with older or high-power devices that aren’t happy with only 3V.
Adafruit Feather RP2040 SCORPIO – 8 Channel NeoPixel Driver: If there is one thing Adafruit is known for, its mega-blinky-fun-rainbow-LEDs. We just love sticking NeoPixels anywhere and everywhere. When we saw the new ‘PIO’ peripheral on the RP2040 from Raspberry Pi, we just knew it would be perfect for driving large quantities of NeoPixels. So we created this board, the Adafruit Feather RP2040 SCORPIO, designed specifically for NeoPixel (WS2812) driving but also good for various other PIO-based projects that want to take advantage of the Feather pinout with 8 separate consecutive outputs (or inputs).
