Just search for Arduino CH340 driver and you will find a number of sources for drivers depending on what Windows or Mac operating system you are using. If you have any issues with connecting to the board, you may need to download a driver. The board uses the CH340 chip for USB communications. These are nice compatible assemblies with very good build quality. Refer the the Arduino documentation for all possible functions for the pins. The attached Mega 2560 board pin-out shows the most commonly used functions for the pins, but some pins can support other functions. Our 7.5V AC adapter works extremely well for powering these boards. Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat. If an external supply is used, it is recommended to use a supply between 7-12V. The power source is selected automatically if both are available. The Mega 2560 operates at 5V which can be supplied via an external power supply or through the USB port connection. 16 Analog inputs that can also be used as digital I/O for a total of up to 70 digital I/O.Key Features of MEGA 2560 R3 with CH340 USB: Mega 2560 R3 with CH340 USB (Arduino Mega 2560 R3 compatible).The Mega 2560 R3 provides a large amount of I/O and memory and is ideal for larger projects Package Includes: The pins on the RAMPS board are specified here.The Mega 2560 R3 is an Arduino compatible board that uses the CH340 USB device for the lowest cost. The RX pin must be connected to a pin on the RAMPS that supports interrupts.ĭepending on your driver type the exact pin may be different. It is no different than UART control on a RAMPS-based 3D printer, just using different pins on the RAMPS board. There is a guide here for how to assemble the cables. To wire TX only - you only need to connect the appropriate TX pin of the RAMPS board to the UART pin of each applicable driver.įor TX and RX, you need a specific jumper that uses a single wire to the driver split to both the TX and RX pins of the RAMPS. This is done with short cables from pins on the drivers to pins on the RAMPS board. ![]() UART requires communication wiring between the drivers and the Arduino (RAMPS) board. Here, AVR stands for Audio Video Recorder and RISC. The Mega 2560 is based on AVR RISC Architecture. Instructions like current settings, microstepping and others can be sent directly to the driver.Įvery TMC22 supports this, however with some manufacturers you have to manually enable it by soldering a small bridge.īTT TMCs always have this enabled, but if you use any other brands and have issues getting UART to work see the UART wiring page The Pinout of Arduino Mega is shown below: The description of pins present on the Arduino board are listed below: ATmega2560 Microcontroller - The Atmega2560 is a CMOS (Complementary Metal Oxide Semiconductor) low powered 8-bit microcontroller. UART describes a communication between the MCU and driver. Refer here for which motor is connected to which position on the RAMPS board. Generate your configuration using the OAT Firmware Configurator and choose the correct board.
