Its orange LED is on D13 and its RGB LED lights each color when its pin is LOW. Mokxi builds it with GPIO pin numbers, and WiFi joins a simulated network.

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 One Xtensa LX7 core at 240 MHz, the DevKitC-1 model whole GPIO D0 to D13, A0 to A7, B0 and B1, with the Nano’s names defined for your sketch ADC1 A0 to A7 The LEDs The orange LED on D13, and red, green and blue of the RGB LED, lit on LOW UART0 and USB Both wired to the serial monitor WiFi, simulated WiFi.h over a network written in software: no radio, no 802.11, and real internet only when you sign in and switch it on ### Not modeled - Arduino pin numbering: sketches are built by GPIO number, so write D13 rather than 13. - VIN and the board’s regulator: VIN is left open. - The second core, the PSRAM, Bluetooth and a real radio.

Projects ## Every built-in project on the Nano ESP32 Each has its own page with the circuit running, the code and a parts list. - Nano ESP32 blink Beginner Learn ## Tutorials that use this board Each one ends in a running circuit, on this same board. - The Nano ESP32 pinout: D and A pins as GPIO numbers ## 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 by GPIO number, as the IDE does with Pin Numbering set to "By GPIO number (legacy)". 13 is GPIO 13, which is A6. Write D13 or LED_BUILTIN, which mean the same pin under either setting. Which way is the RGB LED wired? Each color lights when its pin is LOW: digitalWrite(LED_RED, LOW) turns red on. Does a classic Nano sketch run on it? If it uses the D and A names, mostly: the pins sit in the same places. It runs at 3.3 V, and it is a different chip, so register-level AVR code does not.
