The RedBoard Turbo uses the ATSAMD21G18, which is an ARM Cortex M0+, 32-bit microcontroller that can run at up to 48MHz. With 4MB of external flash memory and a UF2 (USB Flashing Format) bootloader, the RedBoard Turbo provides an economical and easy to use development platform.
The RedBoard Turbo can be flashed over the Mass Storage Class (MSC) just like a removable flash drive, thanks the the UF2 bootloader. With this bootloader, the RedBoard Turbo shows up on your computer as a USB storage device without having to install drivers and can be used with CircuitPython.

This is the latest stable release of CircuitPython that will work with the RedBoard Turbo.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the RedBoard Turbo.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.
All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
