Arduino Nano RP2040 Connect simulator, the RP2040 on a Nano

The Nano RP2040 Connect is the Pico’s RP2040, a Cortex-M0+ at 133 MHz, on the classic Nano’s outline with the Nano’s pin names and an LED on D13. Mokxi runs the RP2040 and its pins; the radio module, the IMU and the microphone on the board are not modeled, and the page says which is which.

The model

What is modeled

Taken from the board's own contract document and put in plain words, with what is missing beside it.

Modeled

Core
The RP2040’s Cortex-M0+, the Pico model whole
GPIO
D0 to D13 and A0 to A5, with the Nano’s names defined as GPIO numbers
PWM
On any pin
The LED
D13, GPIO 6, lit when HIGH, as LED_BUILTIN
UART0
TX and RX, wired to the serial monitor

Not modeled

  • The NINA-W102 module: no WiFi, no Bluetooth, no RGB LED, and A6 and A7, which are its pins.
  • The LSM6DSOX IMU and the crypto chip on the I2C bus, and the PDM microphone.

Each of these opens in the editor exactly as it is drawn here.

Projects

Every built-in project on the Nano RP2040 Connect

Each has its own page with the circuit running, the code and a parts list.

Libraries

Arduino libraries that compile as they are

Paste a tutorial that includes one of these and it builds. For any other library, the build names the Mokxi header that does the same job.

Servo.h
attach, write, writeMicroseconds, read, detach, on any pin
Wire.h
I2C as a master; Wire.begin() puts it on A4 (SDA) and A5 (SCL)
SPI.h
transfer and transactions, on the board’s usual SPI pins
EEPROM.h
read, write, update, get, put and EEPROM[i], kept in 4 KB of RAM, which a reset clears: this board has no EEPROM to write
LiquidCrystal_I2C.h
the 16x2 LCD behind its I2C backpack
Adafruit_GFX.h and Adafruit_SSD1306.h
the 128x64 I2C OLED: text, pixels, lines, rectangles, circles, triangles and bitmaps
Adafruit_NeoPixel.h
WS2812 strips and panels
DHT.h
the DHT11 and DHT22: temperature, humidity and the heat index, as floats you can print

And 15 more, 23 in all: OneWire.h and DallasTemperature.h; Adafruit_BME280.h, Adafruit_BMP280.h and SparkFunBME280.h; RTClib.h; Adafruit_SHT31.h; Adafruit_PCF8591.h; Adafruit_ADXL345_U.h; LedControl.h; Adafruit_LEDBackpack.h; Adafruit_TCS34725.h; Adafruit_SGP30.h; Adafruit_INA219.h; Adafruit_ADS1X15.h; Adafruit_MCP23X17.h; Bounce2.h; HX711.h.

Questions

Is it free?

Yes. Every board and every part is on the free plan, with no account needed.

Why does digitalWrite(13, HIGH) not light the LED?

Because Mokxi builds this board the way the arduino-pico core does, by GPIO number: 13 is GPIO 13, which is A5. Write D13 or LED_BUILTIN.

Does WiFiNINA work?

No. The radio module is not modeled, so the WiFi and Bluetooth libraries have nothing to talk to.

Does the 5V pin give 5 V?

Not until the board’s VUSB jumper is bridged, which it is not out of the box. Here it is open.

Try it on your own firmware

What you build here runs on the board on your desk, unchanged. Nothing to install and no account needed.
