We have the manufacture factory, making productions and selling by ourselves. So we will regulate the quality of our productions by ourselves for you. We’d like to receive your valuable suggestions for our products and make your idea come true. This version is optimized in the original version, mainly for customers under the functional requirements for product quality and high case designed both to make sure consistent and compatible with the original, but also easy to use. Microcontroller: ATmega2560 Compatible with Arduino IDE Operating Voltage: 5V Input: Voltage(really useful) : 7-12V Input Voltage (limits) : 6-20V Digital I/O Pins: 54 (of which 15 provide PWM output) Analog Input Pins: 16 DC Current per I/O Pin: 40 mA DC Current for 3. 3V Pin: 50 mA Flash Memory: 256 KB of which 8 KB used by bootloader SRAM: 8 KB EEPROM: 4 KB Clock Speed: 16 MHz Package includes: 1 x Mega 2560 ATmega2560-16AU Board (Arduino-compatible) 1 x USB cable
Make sure this fits by entering your model number.
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 with reference to the AREF pin and two other new pins placed with reference 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 is a not connected pin, that may be 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 incorporates everything needed to make stronger the microcontroller; simply connect it to a pc with a USB cable or power it with an AC-to-DC adapter or battery to get started.
