Arduino Uno R3 – Genuine Microcontroller Board BX14,R11

DescriptionThe Arduino Uno R3 is the most popular and beginner-friendly development board used in electronics, robotics, and programming projects. It is based on the ATmega328P microcontroller and offers a simple USB interface, 14 digital I/O pins, 6 analog inputs, and built-in support for the Arduino IDE.This board is perfect for students, hobbyists, makers, engineers, and anyone learning embedded systems. At Faranux Electronics, we provide only genuine, high-quality Arduino boards with reliable local support.Arduino Uno R3 Key FeaturesMicrocontroller: ATmega328P 8-bit AVR MCU with pre-loaded Arduino bootloaderOperating Voltage: 5 V (logic level)Input Power: Recommended 7–12 V (via barrel jack)USB Interface: USB Type-B for programming and powerDigital I/O Pins: 14 (6 PWM capable)Analog Inputs: 6 (A0–A5)Clock Speed: 16 MHzMemory: 32 KB Flash (0.5 KB used by bootloader), 2 KB SRAM, 1 KB EEPROMConnectivity: ICSP header for SPI programmingExtra: Reset button, power LED, TX/RX communication LEDsFeatures That MatterEasy to program via Arduino IDE on Windows, Mac, or LinuxExtensive community support & tutorials make it one of the most supported boards in the worldCompatible with hundreds of shields and modules for sensors, motors, displays, and connectivityRemovable ATmega328P Chip (A Key Advantage of the Uno R3)One unique benefit of the Arduino Uno R3 is that it uses a removable, socketed ATmega328P microcontroller chip, unlike many newer development boards that use soldered surface-mount MCUs.This simple but powerful feature makes the Uno R3 ideal for education, prototyping, repairs, and standalone deployment.Why the Arduino Uno Removable Chip Matters1. Easy ReplacementIf the board becomes damaged due to wiring errors, short circuits, or incorrect code upload, the ATmega328P chip can be replaced at a very low cost — without replacing the entire board.2. Burn Bootloaders / Program Chips ExternallyYou can remove the ATmega328P and program it using:An external AVR programmerAnother Arduino as ISPA dedicated ICSP toolThis makes the Uno R3 valuable for learning low-level microcontroller programming.3. Use the Chip for Your Own Custom CircuitsYou can program the chip on the Uno, remove it, and plug it into:BreadboardsCustom PCBsMinimalist standalone Arduino circuitsThis helps reduce cost in final projects while still leveraging Arduino libraries and code. Refer to the circuit in here.4. Beginner-Friendly and RepairableStudents often make mistakes when wiring circuits. The removable DIP-package microcontroller means they can simply replace the chip and continue learning — keeping the Uno R3 as one of the most classroom-friendly boards.ResourcesArduino IDE downloadDatasheetPackage includes: 1×Arduino Uno R3 Board with logo 1×Arduino Uno Cable (USB-A To USB-B)
