senseBox MCU

Image of Board

The senseBox-microcontroller (MCU) is specially designed and developed for the senseBox project. The three main advantages and characteristics of the microcontroller are: expandability, speed, and efficiency.


The processor is based on the ARM Cortex-M0+ processor from Microchip’s SAM D21 family.


Sensors and actuators are addressed via proven interfaces such as I2C, UART and digital I/Os with a robust JST connector system (5V tolerant).

Data transmission

UART or SPI modules are offered via the two XBee compatible sockets. Optionally, the data transmission can be performed via WLAN, LAN, or LoRa in real time. Alternatively, the data can be stored on a micro SD card.

Absolute Newest

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.

Past Releases

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.
