Skip to product information
The ELEGOO UNO R3 is a microcontroller board based on the ATmega328P and CH340C chipset, delivering 100% Arduino UNO R3 compatibility. This board features 14 digital input/output pins (6 PWM-capable), 6 analog inputs, and operates at 16 MHz with a ceramic resonator for stable clock performance.
Key specifications include 32 KB of flash memory (with 0.5 KB reserved for bootloader), 2 KB of SRAM, and 1 KB of EEPROM for data persistence. The board comes pre-programmed with a bootloader, enabling direct code uploads via USB without external hardware programmers.
Connectivity and interface options include dedicated USB connection, power jack for AC-to-DC adapters or battery power, ICSP header for advanced programming, and integrated reset button. The board features standard RX and TX LEDs for real-time USB transmission feedback.
Design enhancements include SDA and SCL pins positioned beside the AREF pin, an IOREF pin for shield voltage adaptation, and additional reserved pins near the reset button for future expansion. Full shield ecosystem compatibility ensures seamless integration with existing and emerging Arduino accessories.
Ideal for embedded systems development, IoT prototyping, robotics, and educational applications, this board combines professional-grade performance with maker-friendly accessibility.
