Description:
Attention Arduino enthusiasts! Are you ready to take your skills to the next level? Introducing the SparkFun RedBoard Turbo - a powerful and feature-packed alternative to older 8-bit/16MHz microcontrollers. At its core, the RedBoard Turbo uses the ATSAMD21G18 ARM Cortex M0+, a 32-bit microcontroller that can run at speeds of up to 48MHz. With a generous 4MB of external flash memory and a convenient UF2 (USB Flashing Format) bootloader, this development platform is perfect for those looking for more power than the classic RedBoard.
The SparkFun RedBoard Turbo comes equipped with a variety of features to enhance your Arduino experience, including a USB interface for programming and power, a Qwiic connector, an RTC crystal, an addressable RGB LED, a 3.3V regulator, and much more. It's easy to power the RedBoard Turbo using a USB port on your computer or by connecting it directly to a wall outlet with the 5V tolerant barrel jack. And if you're not near a USB port, don't worry - the RedBoard Turbo also has a LiPo Battery connector for use with a single-cell 3.7-4.2V lithium-polymer battery. Plus, with the MCP73831 charge controller, you can charge your battery at a rate between 15mA and 500mA by adjusting the resistor value between 66k and 2k. By default, the board is set to charge at a rate of around 250mA.
In addition to its impressive specs, the RedBoard Turbo is also compatible with the Arduino 1.0 footprint standard and includes separate SPI and I2C headers. And with the UF2 bootloader, you can easily flash the RedBoard Turbo over the Mass Storage Class (MSC) just like a removable flash drive - no drivers needed! The RedBoard Turbo even shows up on your computer as a USB storage device, making it simple to program with the Arduino IDE or other languages like CircuitPython or MakeCode. Upgrade your Arduino game with the SparkFun RedBoard Turbo.
Note: The barrel jack connection on the RedBoard Turbo has a lower input voltage than most Arduino development boards. Make sure that you are using a power supply below 6V. Please be aware that the RedBoard Turbo is also a 3.3V device and not a 5V one like the original RedBoard.
