The SparkFun RedBoard Qwiic is an Arduino-compatible development board that uses a few of the features that they loved about Arduinos of the past while also incorporating a few key improvements over the original RedBoard. The best part about the RedBoard Qwiic is that (as the name implies) it utilises the handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!

Of course, they didn’t just add a Qwiic Connector to the board, lets go over all the new additions that make the SparkFun RedBoard Qwiic unique! With the improved AP2112 voltage regulator, this Reboard gains a more robust 3.3V regulator that provides it more power to daisy chain multiple Qwiic boards and sensors, sourcing up to 600mA of current. To help support the micro USB connector (updated from a Mini USB), the CH340C Serial-USB converter IC allows the RedBoard Qwiic should reduce the need for you to manually install drivers allowing for newer operating systems to automatically recognise and install the drivers for the board. Lastly, they have made sure to add a few solder jumpers to the board. The jumpers for the A4 and A5 pins are tied directly to the I2C bus and can be used to disconnect the logic level converters from the pins while the voltage level jumpers can switch the RedBoard Qwiic from a 3.3V device to a 5V device (no logic level converter needed).

The SparkFun RedBoard Qwiic can be programmed over a USB Micro-B cable using the Arduino IDE: Just plug in the board, select “Arduino UNO” from the board menu and you’re ready to upload code. RedBoard Qwiic has all of the hardware peripherals you know and love: 20 Digital I/O pins with 6 PWM pins, UART, SPI and external interrupts. SparkFun have also broken out the SDA, SCL and IOREF pins that showed up on the UNO R3, so the RedBoard Qwiic will be compatible with future shields (if you choose to use them). You can power the SparkFun RedBoard Qwiic over USB or through the barrel jack. The on-board power regulator can handle anything from 7 to 15VDC.
