• Arduino is an open-source hardware, software, and content platform with a worldwide community of over 30 million active users

Arduino

• NEW IMPROVEMENT: Clear prints on the female header connector, more precise and easier to use the wire.
• The ELEGOO UNO R3 BOARD now uses an ATMega16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory.
• Control using ATMEL ATMEGA328P chip(the same with Arduino UNO R3)
• 100% compatible with the Arduino IDE and RoHS Compliant
• We have always cared about the customer experience and improve the product function details.

ELEGOO

• Free PDF tutorial(more than 22 lessons) and clear listing in a nice package
• The most economical kit based on Arduino platform to starting programming for those beginners who are interested.
• Lcd1602 module with pin header (not need to be soldered by yourself)
• This is the upgraded starter kits with power supply module, 9V battery with dc
• High quality kite with UNO R3. 100% compatible with Arduino UNO R3, MEGA 2560 R3, NANO.

ELEGOO

• Original ATmega328P CH340 chip is used. Improved new version CH340G Replace FT232RL.
• LAFVIN Nano V3.0 card is 100% compatible with the Nano card, and fully compatible with Windows, Mac and Linux operating system.
• Works the same as original Nano, runs perfectly on programming software.
• Using Atmel Atmega328P-AU MCU, Support ISP download; Support USB download and Power.
• LAFVIN Nano CH340 controller is a compact board similar to the R3 board, smaller and breadboard-friendly than Diecimila.

LAFVIN

• The Mega is 100% compatible with Arduino IDE and most shields designed for the Arduino mega2560 r3，RoHS Compliant
• The chip is Atmega2560-16au and Atmega16u2, same with the official version.
• Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Due that operate with 3. 3V. The second one is a not connected pin, that is reserved for future purposes.
• Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack)
• It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

HiLetgo

• 【Powerful CPU] Seeeduino XIAO development board carries ARM Cortex-M0 + 32bit 48MHz microcontroller (SAMD21G18) and low power consumption. The clock frequency is 48MHz, which is three times that of Arduino Uno and Arduino Nano. In addition, this Arduino IDE compatible board is equipped with 256KB flash memory and 32KB SRAM. We have prepared a wiki so that customers can get started quickly. (Wiki: https://wiki.seeedstudio.com/Seeeduino-XIAO/)
• [Flexible Compatibility] The Seeeduino XIAO development board is Fully compatible with the Arduino IDE ,you can easily develop some small projects with the help of the large and comprehensive Arduino library. As it has a 2.54mm pin pitch, it is an Arduino microcontroller that can be used even when inserted into a breadboard.
• [Ultra Small] This Arduino IDE compatible board is as small as your thumb (about 20x17.5mm) and can be used to make small devices such as wearable devices. The Seeeduino XIAO Development Board is the smallest Arduino compatible board in the Seeeduino series.
• [Multiple development interfaces] 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, 1 I2C interface, 1 UART interface, 1 SPI interface. Attention:All the I/O pins are 3.3V, please do not input more than 3.3V, otherwise, the CPU may be damaged.
• [USB Type C Support] Seeeduino XIAO supports the USB Type-C interface which can supply power and download code. Type-C is more robust than Micro USB.And there are power pads at the back of the XIAO which support battery and make it designed for wearable devices to become realistic.
