This eliminates the need for a secondary processor, allowing the Micro to function directly as a mouse, keyboard, or a virtual serial\/COM port when connected to a computer. This feature unlocks exciting possibilities for human interface device (HID) projects and more.\u003c\/p\u003e\n\u003csection id=\"shopify-section-template--17226866294951__80b23d23-dbc1-4fdc-a89d-75cc3b5bb6c6\" class=\"shopify-section section\"\u003e\n\u003cdiv class=\"color-background-2 gradient\"\u003e\n\u003cdiv class=\"section-template--17226866294951__80b23d23-dbc1-4fdc-a89d-75cc3b5bb6c6-padding\"\u003e\n\u003cdiv class=\"page-width\"\u003e\n\u003cdiv class=\"rte\"\u003e\n\u003ch2\u003e\u003cspan\u003eSpecifications:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eMicrocontroller: ATmega32U4\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOperating Voltage: 5V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInput Voltage: 7-12V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDigital I\/O Pins: 20\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePWM Channels: 7\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAnalog Input Channels: 12\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDC Current per I\/O Pin: 20 mA\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDC Current for 3.3V Pin: 50 mA\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFlash Memory: 32 KB (ATmega32U4) of which 4 KB used by bootloader\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSRAM: 2.5 KB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEEPROM: 1KB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eClock Speed: 16 MHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLED_BUILTIN: 13\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThe Arduino Micro board is built with an ATmega32U4 microcontroller.\u003c\/li\u003e\n\u003cli\u003eThis Arduino Micro features 20 digital input\/output pin and a 16 MHz crystal oscillator.\u003c\/li\u003e\n\u003cli\u003eSimply connect it to a computer with a micro USB cable to get started.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan\u003ePin Description:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/content.arduino.cc\/assets\/Pinout-Micro_latest.png\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eUseful Link:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003e\u003ca href=\"https:\/\/content.arduino.cc\/assets\/Pinout-Micro_latest.pdf\" rel=\"noopener\" target=\"_blank\"\u003ePinout Diagrams\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003ePackage Included:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003e1 x Arduino Micro\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"Arduino","offers":[{"title":"Default Title","offer_id":43062030631017,"sku":"ARD-004","price":2145.82,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/4229\/5401\/files\/NewProject-2025-07-10T175214.588.webp?v=1774509057"},{"product_id":"official-arduino-mkr-wifi-1010-development-board-esp32-u-blox-nina-w102-module","title":"Arduino MKR WIFI 1010 Development Board","description":"\u003ch2 style=\"font-size:1.4em;font-weight:700;margin:0 0 12px;line-height:1.4;\"\u003eArduino MKR WiFi 1010 — 32-bit ARM Cortex-M0+ — Wi-Fi \u0026amp;

ADC resolution improves from 10-bit to 14-bit, and a 12-bit DAC is added where the R3 had none. Wi-Fi 4, Bluetooth 5, a 12×8 LED matrix, CAN bus, RTC, OP AMP, and a Qwiic connector are all new additions. The 5 V form factor, pinout, and Arduino IDE workflow remain identical, so existing projects migrate with minimal code changes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: #1a1a1a; border-left: 3px solid #BAFF02; border-radius: 4px; padding: 18px 20px; margin: 0 0 12px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #baff02; margin: 0 0 10px; line-height: 1.5; font-size: 0.97em;\"\u003eHow many GPIO pins and communication interfaces are available on the Arduino UNO R4 WiFi EK?\u003c\/p\u003e\n\u003cp style=\"margin: 0; line-height: 1.75; font-size: 0.94em; color: #e0e0e0;\"\u003eThe board exposes \u003cspan style=\"color: #baff02; font-weight: 600;\"\u003e14 digital I\/O pins\u003c\/span\u003e (D0–D13, with 6 supporting PWM) and \u003cspan style=\"color: #baff02; font-weight: 600;\"\u003e6 analog input pins\u003c\/span\u003e (A0–A5) that also function as digital I\/O.
