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. Start building free - 5 peripheral areas modeled - 1 project ready to run - Real time on your own machine Hold the button The board is running real firmware right now. Click it to open the circuit in the editor. 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. Start here ## Open one and press Run 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. - Nano RP2040 button Beginner 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. Also here ## The other boards Every one of these runs today, and every one is free.
