The RedBoard Turbo uses the ATSAMD21G18, which is an ARM Cortex M0+, 32-bit microcontroller that can run at up to 48MHz. It has an impressive 4MB of external flash memory and a UF2 (USB Flashing Format) bootloader.
The SparkFun RedBoard Turbo has been equipped with a USB interface for programming and power, a Qwiic connector, an RTC crystal, WS2812-based addressable RGB LED, 600mA 3.3V regulator, a LiPo battery connector and charger. Be aware that the RedBoard Turbo is a 3.3V device and not a 5V one like the original RedBoard.
With the UF2 bootloader, the RedBoard Turbo shows up on your computer as a USB storage device without having to install drivers. From the Arduino IDE, you’ll still need to select the correct port on your machine, but you can just as easily use another programming language such as CircuitPython or MakeCode.
