Arduino Nano 33 BLE
The Arduino Nano33 BLE is a very small ARM development board based on the Nordic Semiconductor nrf52840 processor.
There is also the Arduino Nano33 BLE Sense which is the exact same board but with additional onboard sensors.

Documentation for the machine package for the Arduino Nano33 BLE
Installing BOSSA
In order to flash your TinyGo programs onto the Arduino Nano33 BLE board, you will need to install the “bossac_arduino2” command line utility which is a special build of the BOSSA command line utilities.
macOS
If you have a Mac computer with an Intel processor, download the bossac_arduino2 program from http://downloads.arduino.cc/tools/bossac-1.9.1-arduino2-osx.tar.gz
Extract the downloaded file to a directory on your computer.
Make sure to add that directory into your PATH.
Linux
Download the bossac_arduino2 program from http://downloads.arduino.cc/tools/bossac-1.9.1-arduino2-linux64.tar.gz
Extract the downloaded file to a directory on your computer.
Make sure to add that directory into your PATH.
Windows
Download the bossac_arduino2 program from http://downloads.arduino.cc/tools/bossac-1.9.1-arduino2-windows.tar.gz
Extract the downloaded file to a directory on your computer.
Make sure to add that directory into your PATH.
Flashing
Once you have installed the needed BOSSA command line utility, as in the previous section, you are ready to build and flash code to your Arduino Nano33 BLE board.
CLI Flashing
-
Plug your Arduino Nano33 BLE board into your computer’s USB port.
-
Build and flash your TinyGo code using the
tinygo flashcommand. This command flashes the Arduino Nano33 BLE with the blinky1 example:tinygo flash -target=nano-33-ble examples/blinky1 -
The Arduino Nano33 BLE board should restart and then begin running your program.
Troubleshooting
Instructions needed here.
Bluetooth
Nordic Semiconductor’s SoftDevice (s140v7) must be flashed first to enable use of bluetooth on this board.
SoftDevice overwrites original bootloader and flashing method described above is not avalable anymore.
Instead, please use debug probe and
flash your code with nano-33-ble-s140v7 target.
Notes
You can use the USB port to the Arduino Nano33 BLE as a serial port. UART0 refers to this connection.
