CircuitPython on an ARM Cortex M4 in almost 1 square inch! This “Just Add Solder” castellated module is perfect for incorporating into your own project. The CircuitBrains Deluxe board footprint is small enough to fit into narrow spaces and wearable projects.
NOTE: This board does not have a USB connector for the native USB. Native USB is broken out on the header/castellations and therefore requires a non-standard USB connection such as mounting to a motherboard PCB.
- Dimensions: 29 x 29 x 3.5 millimeters / 1.15 x 1.15 x 0.15 inches
- Atmel ATSAMD51J19A Microcontroller (32-bit ARM Cortex M4)
- 120 MHz
- 192 KB SRAM
- 512 KB Flash
- 8 MB QSPI Flash
- Onboard 3.3V LDO Regulator
- Power and Status LEDs
- Breakouts for SPI and I2C
- Breakouts for 14 Analog and 19 Digital Inputs/Outputs

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
Update UF2 Bootloader
Latest version: v3.13.0
The bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).
It is not necessary to update your bootloader if it is working fine. Read the release notes on GitHub to see what has been changed. In general, we recommend you not update the bootloader unless you know there is a problem with it or a support person has asked you to try updating it.
To update, first save the contents of CIRCUITPY, just in case. Then double-click the reset button to show the BOOT drive. Drag the update-bootloader .uf2 file to the BOOT drive. Wait a few tens of seconds for the bootloader to update; the BOOT drive will reappear. After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
