HW-283 MEGA2560 R3 REV3 ATmega2560-16AU CH340G Board ON USB Cable Compatible for Arduino No USB Line

Specifications:Model: HW-283Microcontroller: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 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 MHzSize: 101*53*1.5mm Features: Thoroughly solved the incompatible instability of the traditional 2560 boards on the win7 and win8 systems.With the main control chip ATMEGA2560-16AU unchanged, replaced the USB chip 16u2, Arduino project team launched the use of ATMEGA8U2, ATMEGA16U2 version of the product has its own ideas, in most applications, these USB interface chips just as a serial port "brush machine" and communications.With professional USB chips, the cost can be reduced and the application can be well satisfied.
