KEYESTUDIO Mega 2560 R3 Board for Arduino Projects with USB Cable

Introduction:
keyestudio Mega (core to ATmega2560) is a development board (used with16MHz crystal oscillator ) of microcontroller. There are 54 I/O (input/output ) digital interfaces (of which 15 are PWM outputs), 16 analog inputs and 4 UART (hardwareserial ports). With its bootloader, program can be downloaded directly with USB and you don’t need to use other external programmer. It can be powered directly by USB, or AC-to-DC adapter and battery.

2Design of Power Supply :
There are two choices (direct power supply trough USB or external power supply) for the power supply system of Mega, and they can be Automatic switched.
External power supply can be AC-to-DC adapter or battery.
Lit rang of voltage of this control board is 6V~12V, but if the supplied voltage is greater than 12V, the voltage stabilizing device will be likely overheated and overheat protection and damaging MEGA will be more likely to occur.
So we suggest the power supply should be 6.5~12V in operation and recommended supply is 7.5 or 9V.

keyestudio MKS GEN 1.4 3D Printer controller Board /RAMPS 1.4 + Mega 2560 for Arduino (Black &Environmental-protection)

Intruduction
Keyestudio 3D MKS Gen V1.4 printer motherboard control board combines and improves the assets solution of the RAMPS 1.4 and Arduino Mega 2560 board on a fantastic single board.
Keyestudio 3D MKS Gen V1.4 printer motherboard control board is an optimal 3D printer controller solution for your Reprap 3D printer.

Features
Integrate 2560 and ramps1.4 in a board, to solve the complicated interfaces and broken problem of Ramps1.4 combination.
Replaceable motor driver, support 4988 driver and 8825 driver.
Circuit board using high-quality 4-layer board, and specially dealing with thermal optimization; ramps is a 2-layer board.
Using high-quality MOSFET tube, with better heat dissipation.
Using a dedicated power chip to support 12V-24V power input, to solve the problem of Ramps voltage converted into chip heating.
To accept 24V input, hot bed current can be reduced to 1/4 under the same system power, effectively solve the heating problem of hot bed MOS tube.
Firmware can use open-source firmware Marlin, and its configuration is exactly the same as ramps1.4, which can directly replace Ramps1.4.
Can directly connect to Ramps1.4,2004LCD control board and 12864LCD control board.
Set aside the motor pulse and direction output port, convenient to facilitate external high current to connect external high current (such as 2A, 5A) motor drive circuit.
Reserve the Servos, AUX-1, AUX-2 interfaces on Ramps1.4, providing three 5V output, three 12V output interface.
This board is an upgrade part of the MKS Gen V1.2 board, improving the performance of power protection and USB communication stability.

Package Included: 
1 x MKS-Gen V1.4 Controller 
1 x Usb Cable
