ELEGOO UNO R3 Board for Arduino [A000066]

ELEGOO STEM kits provide all the necessary components, sensors, wires, and boards for you to get started with programming, learning electronics, and creating IoT projects. We strive our best to make STEM education easy to learn and accessible to the young generation.

Established in 2011, ELEGOO is a thriving technology company dedicated to open-source hardware research & development, production and marketing. Our own Quality Management Team will secure the premium quality of our products and we would like to receive your valuable suggestions for our products and make your idea come true.

The ELEGOO UNO R3 puts SDA and SCL pins beside the AREF. Besides, there are two new pins placed near the RESET pin. One is the IOREF that allows the shields to adapt to the voltage provided from the board and the other one is reserved for future purposes. The ELEGOO UNO R3 works with all existing shields and can adapt to new shields which use these additional pins.

The ATmega328 on the UNO R3 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. The ATmega328 has 32 KB (with 0.5 KB occupied by the bootloader). It also has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library). It use the same ATmega16U2 as official Arduino UNO R3. The ATmega16U2 firmware source code is available in the official repository. The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be activated.

The ELEGOO UNO R3 board can be powered via the USB connection or with an external power supply. Excellent welding and production quality to make sure satisfied customer experience. Clearly printed pin names on the header connector, more precise and much easier to use the wires.

ELEGOO's kits are best-practice for beginners who have no appropriate technical tools to learn about electronics, as they are 100% compatible with Arduino. Chris, the founder of ELEGOO, found that most enterprises in the STEM industry focused on the hardware of open-source electronics and did not have tools to create a complete product by combining electronic hardware and structural shells.

We have an excellent R&D team, constantly upgrading and improving products, and an after-sales service team for quick support. Our products, including ELEGOO MEGA R3, ELEGOO UNO R3 Project Starter Kits, ELEGOO Mega 2560, ELEGOO UNO R3 Project Complete Starter Kit, ELEGOO UNO R3 Project Smart Robot Car Kit V4, and ELEGOO Upgraded 37 in 1 Sensor Modules Kit, all come with detailed tutorials and are well-received by customers, with high ratings of 4.5 to 4.8 out of 5 stars.
