Features: brand new and high quality Embed version of Mega2560 /ATmega2560, for Mega2560 board. Built on the Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G. Board have compact size 12x8x3cm/4.72x3.15x1.18in. It is good solution, to make your final project on solder proto-board. Board for functionality similar to the Mega2560. It is embed board, but the same stable, and uses the original chips ATmega2560 (16 MHz). The board used the chip CH340G as converter UART-USB. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer). You can supply power to board through the Micro USB connector or to power pinheaders. The voltage regulator (LDO) can deal with incoming voltage from 6V to 9V (peack 18V) for DC. Output current for 5V - about 800mA, for 3.3V - about 800mA Specifications: CH340G Replace ATega16U2 Microcontroller:ATmega2560 Operating Voltage:5V Input Voltage (recommended):7-12V Input Voltage (limits):6-20V Digital I/O Pins:54 (of which 15 provide PWM output) Analog Input Pins:16 for DC Current per I/O Pin:40 mA for 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 Size: approx 12x8x3cm/4.72x3.15x1.18in. Package Includes: Prototype PCB, Terminal Blocks, Female Header Sockets note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-3mm measuring deviation due to manual measurement.
