[MKS Eagle V1.0] 3D Printer Control Board With Tmc2209 Driver, Supports 2 Extruder,Support Marlin & Klipper

The Controller board, also known as the main board or motherboard, are PCBs that read and carry out the gcode by commanding motors and presume better printing experiences with many functions. Today, the most common add-ons by default include filament-run-out sensor, Power-off resume, auto-leveling sensor, expansion ports(12c, SPI, UART, CAN), etc...

1)MCU
2)Motor driver (slots)
3)Motor ports
4)Power supply interface
5)Hot-end/hotbed heater interface
6)Thermal runaway interface
7)End stop ports
8)Fan ports
9)Display port
10)TF/SD card slot
11)Communication ports(USB-C interface, WiFi, CAN, etc.)

1)The first thing you should look at is the Processor. What is its Architecture (32-bit or 8-bit)? How fast could it proceed(Main Frequency, RAM) and how large could it storage (Flash size)?
2)Could you run Marlin/RepRap/Klipper on this board?

3)Number of a-xis
If your 3d printer have multiple extruders or z-axis motors, you need pay attention to the number of motor interfaces, motor driver slots, hot-end heater slots, hot-end thermal port, and limit-switch ports.
* Some MKS boards can share a stepper driver with 2 z-axis motors.

4)Stepper motor matters
Most MKS 3d printer boards are compatible with A4988, TMC2208/TMC2225, and TMC2209/TMC2226. If the board have external Stepper driver ports, you can connect stepper drivers of larger current such as TMC 2160-OC/TMC 2160-57.
5)Wired or wireless communication port or expansion
Does this board communicate in the way you favor? Does the board have USB Type-A port? USB Type-C port? Mini-USB port? Micro USB port? WiFi expansion?

6)Regular add-on
such as filament-run-out sensor, Power-off resume, auto-leveling sensor, expansion ports(12c, SPI, UART, CAN), etc...

Most makers prefer to choose the stepper drivers by themselves since stepper drivers are highly diversified for different needs of current, micro-stepping rate, silences, etc. Also, the cost plays an important role when choosing the stepper driver.
