The ESP32-S2 Mini V1.0.0 WiFi development board is fully compatible with the Arduino IDE. Simply install the ESP32 board support package and you can start uploading sketches just as you would with any other Arduino-compatible board. It also supports MicroPython and Espressif's native ESP-IDF framework.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between Flash and PSRAM on this development board?\u003c\/h4\u003e\n\u003cp\u003eA: Flash memory (4MB on this board) is used for storing your program code and data persistently — it retains data even when the board is powered off. PSRAM (2MB) is additional RAM that expands the working memory available during program execution, allowing you to run more complex applications, handle larger data buffers, and use memory-intensive libraries without running out of heap space.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these boards compatible with D1 Mini shields?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, the S2 Mini V1.0.0 is designed to be physically and electrically compatible with D1 Mini shields, making it easy to use existing expansion shields for sensors, displays, relays, and more with no modification required.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do all 27 I\/O pins support PWM, I2C, and interrupts?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, all 27 digital input\/output pins on the ESP32-S2 Mini V1.0.0 support interrupt, PWM, I2C, and single-wire protocols, giving you maximum flexibility when wiring up sensors, actuators, and communication modules in your IoT projects.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
