BLE-SS Dev Board Multi Sensor

by Switch Science, Inc.

Image of Board

This development board includes a Bluetooth Low Energy-enabled ISP1807 from Insight SiP (based on the nRF52840) and six sensors: acceleration, magnetism, gyro, temperature, humidity and air pressure.

The development board is programmed with a bootloader. You can use the Arduino IDE or Circuit Python to develop your program. It has two switches and two LEDs each that can be used programmatically, and it also has a piezoelectric speaker.

It features a TPS63030 high-efficiency step-up/down converter and runs on CR2025 or CR2032 coin cell batteries. The board outline is the same as the Raspberry Pi Zero, so it can be used in a Raspberry Pi Zero case.


  • ISP1807 based on the nRF52840
  • 9-Axis Sensor (BXM055)
  • Humidity and Temperature Sensor (HDC2010)
  • Pressure Sensor (LPS22HB)
  • Buzzer
  • 2 LEDs (Green and Red)
  • 2 Push buttons
  • CR2032 Coin Battery supports
  • Raspberry Pi Zero compatible board dimensions

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.
