OVM20 Lite - Arduino Board + Ramps + 4x DRV8825 all in one - Staticboards
This board is ideal if you are mounting a 3D printer and you do not want to complicate your life.
It is the natural evolution of the Arduino Mega + RAMPS 1.4 SB. A solution with all the integrated components.
With this plate you’ll save having to buy the Arduino Mega 2560, plus 1.4 RAMPS, and having to connect a pair of drivers for step by step motors.
With OVM20 you have everything in one board.
For the Marlin firmware, the board is a RAMPS 1.4. The pins and connectors coincide precisely, and are 100% compatible
Download the Marlin, and select the board:
# define BOARD_RAMPS_14_EFB
It’s the setup that comes by default.
With this you can configure the Marlin as if it was a RAMPS 1.4 with an extruder, a layer fan, and a warm bed.
Static boards philosophy is to select the quality components. That’s why both the power connectors and the transistors are branded.
Selected to withstand hours of continuous printing, without having to worry that the connectors melt, burn, and have an accident.
