Arduino Mega 2560 Ch340 Schematic. It has 54 digital input output pins of which 15 can be used as pwm outputs. Arduino mega 2560 with ch340 driver.
The atmel mcu atmega16u2 mega 2560 r3 improved version ch340g board is a micro controller board base on the atmega2560. Dc jack power supply. Arduino mega ch340 schematic schematic arduino mega 2560 wiring diagram.
Ch340 is a usb bus convert chip and it can realize usb convert to serial interface usb convert to irda infrared or usb convert to printer interface.
Atmega1280 or 2560 microcontroller i recommend the atmega1280 so you can use arduino ide to program tqfp100 0 5mm pitch to dip adapter momentary push button 6 headers for isp lots of wires flux perfboard 16 mhz crystal if you salvaged chip from arduino mega optional but recommended double sided tape. This card has the same clock speed as the arduino uno but is a real power due to the much larger memory and the number of pins more than doubled. Arduino mega schematic components.
