Features: brand new and high quality Embedded version of Mega2560 /ATmega2560, for Mega2560 board. Built on Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G. The board has a compact size of 12x8x3cm/4.72x3.15x1.18in. It is a good solution for making your final project on a solder protoboard. Board for functionality similar to Mega2560. It is an embedded board, but equally stable, and uses the original chips ATmega2560 (16 MHz). The board uses the CH340G chip as a converter UART-USB. When working at a frequency of 12Mhz, it provides a stable result of data exchange (needs to install drivers to the computer). You can power the board via the Micro USB connector or to the power pin headers. The voltage regulator (LDO) can handle incoming voltage from 6V to 9V (peak 18V) for DC. Output current for 5V - about 800mA, for 3.3V - about 800mA Specifications: CH340G Replaces 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 is used by bootloader SRAM: 8 KB EEPROM: 4 KB Clock Speed: 16 MHz Size: approx. 12x8x3cm/4.72x3.15x1.18in. Note: Due to the different monitor and light effect, the actual color of the item may be slightly different from the color shown on the pictures. Thank you! Please allow 1-3mm measurement deviation due to manual measurement. Package includes: Prototype PCB, Terminal Blocks, Female Header Pins
