This board is the combination of Mega2560 R3 and ramps 1.4. In this case, you do not have any worries on the connection problems. It is compatible with A4988 and 8825 driver which is more flexible. In order to achieve better cooling, the board has the highest quality circuit board and MOSFET. What’s more, we use LM2576 ultra-wide power supply chip which supports 12v-24v power input. In this case, we can solve the heating problem of the Ramps. We will offer you a detailed tutorial including project introduction and their source code.
