SparkFun RedBoard Qwiic ATMega328P Compatible with Arduino Board w/Qwiic Connector and CH340C Serial-USB Converter IC Breadboardable R3 Footprint microcontroller Improved Reset Button

At SparkFun we continually like to innovate, update, and improve even when it comes to our very own development boards. We have multiple versions of the SparkFun RedBoard in our catalog but none of them in an R3 form factor with a Qwiic connector on it to make I2C easy... until now! The SparkFun RedBoard Qwiic is an compatible with Arduino development board that uses a few of the features that we have loved about boards 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 utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!Of course, we 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 recognize and install the drivers for the board. Lastly, we 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).AP2112 Voltage RegulatorA4/A5 Jumpers3.3V to 5V Voltage Level JumperInput voltage - 7-15V20 Digital I/O Pins (6 PWM Outputs and 6 Analog Inputs)ISP Header32k Flash Memory16MHz Clock SpeedAll SMD ConstructionR3 Shield Compatible

• ATmega328 microcontroller with Optiboot (UNO) Bootloader. Rev3 shield compatible.
• Program with a USB Micro-B cable using the Arduino IDE platform: Plug in the board, select “Arduino UNO” and you’re ready to upload code
• Hardware peripherals you know and love: 20 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts
• Broken out the SDA, SCL and IOREF pins, so it will be compatible with future shields Power over USB or through the barrel jack 7 to 15VDC
• The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
