The Arduino Nano 33 BLE Sense is a microcontroller, a small computer that runs a single program.
The Nano uses 3.3V logic. Here is the pinout, a map of all general purpose input/output (GPIO) pins:
Download the Arduino IDE, we recommend the desktop version, which shows up as Arduino once installed.
The IDE (integrated development environment) is a simple tool to write, build and deploy programs.
Follow this guide to get started with the Arduino Nano 33 BLE Sense.
Or just open Tools > Board > Board Manager... and add the Arduino nRF528x Boards (Mbed OS) package.
Then select Tools > Board > Arduino Mbed OS Boards (nRF52840 / STM32H747) > Arduino NANO 33 BLE
Now connect the Nano BLE 33 Sense to your computer via USB and select it in the Tools > Port menu.
Finally, open File > Examples > Basics > Blink and click the ⮕ Upload button.
(Driver issues? Check the guide above or try pressing reset before upload.)
The Arduino language is very similar to C, libraries are written in C++.
This is Blink, the Hello, World! of embedded programming:
int ledPin = 13;
void setup() { // runs once
pinMode(ledPin, OUTPUT); // set up the LED pin
}
void loop() { // runs forever
digitalWrite(ledPin, HIGH); // turn the LED pin on
delay(1000); // wait for 1000ms = 1s
digitalWrite(ledPin, LOW); // turn the LED pin off
delay(1000); // wait again
}
The #MakeZurich 2020 badge has 11 individually controllable Neopixel multicolor LEDs and a SAO connector.
Try this Corona app scanner example, it requires the Adafruit_NeoPixel library and the ArduinoBLE library.
Note: Please disconnect the badge battery before plugging the USB cable into the Nano BLE 33 Sense.
Here are the schematics.
Follow these steps to install an Arduino library.
Or just open Sketch > Include library > Manage libraries... and type the library name.
Then check the File > Examples > LIBRARY_NAME menu in the Arduino IDE.

To use it, follow this tutorial or install the ArduinoBLE library and check the examples.
The Murata B-L072Z-LRWAN1 board can be used as a modem to send data to TheThingsNetwork (TTN).
To use the board as a modem, add these files of the LoRaWANModem "library" by @2ni.
To get your data from the TTN backend, see #MakeZurich software intro.
Wire it to the Nano BLE 33 Sense (or any device with 3.3V UART):
Power both boards via USB.
| Nano | Murata |
|---|---|
| TX | PA10 (RX) |
| RX | PA09 (TX) |
| D3 (RTS) | PB08 |
| D2 (CTS) | PA08 |
| GND | GND |
The Murata board runs Semtech's LoRaWAN soft modem, here is the reference manual.
- Dale Giancono has a nice collection of Nano BLE 33 Sense examples.
- And there are quite some Nano BLE 33 Sense projects on Hackster.io.
The Arduino Uno is a microcontroller.
The Uno uses 5V logic, the pinout is printed right on the board:
Follow the steps in this tutorial (PDF, p.10 - p.41).
Or just select Tools > Board > Arduino/Genuino Uno.
Then plug in the Uno via USB and select it in the Tools > Port menu.
Finally, open File > Examples > Basics > Blink and click the ⮕ Upload button.
Follow these steps to install an Arduino library.
Then check the File > Examples > LIBRARY_NAME menu in the Arduino IDE.

The included gateway is a Tabs Hub that works with TheThingsNetwork.
It's configured as a LoRaWAN gateway, TrackNet/Tabs features and WiFi access point are disabled.
Plug it in via Ethernet, it will open a secure, outgoing connection to the TheThingsNetwork backend.
The EUI is on its back, e.g. for 580011AABBCC register 580011FFFEAABBCC in the TTN console.
The following electronic components are part of the MakeZurich kit.
As a simple rule, before connecting anything, unplug the power / USB cable.
A breadboard allows you to prototype electronic circuits.
Its holes are connected under the hood in columns, plus two rows for ground (GND, black or blue) and power (VCC, red).
Jumper wires allow you to connect the Arduino to additional modules and components on a breadboard.
Basic components like LEDs, resistors and buttons allow you to add input and output capabilities to your Arduino.
50x leds, 1x rgb led, 2x photoresistors, 1x thermistor, 5x diode rectifiers, 5x npn transistor, 1x IC 4N35, 1x IC 74HC595, 10x buttons, 2x buzzers (active and passive), 1x potentiometer, 10x 22pf c. caps, 10x 104 c. caps, 5x e. caps 10uf, 5x e caps 100uf, 100x resistors (5x of each: 10R, 100R, 220R, 330R, 1K, 2K, 5K, 10K, 100K, 1M, pin headers).
