Do not adjust the current when the motor is working. Do not plug the motor when connected to the power, otherwise it is easy to damage the inverter. Before powering on, make sure that the top is positive and the bottom is negative (some positive and negative parts of the adapter may be different). Power is 7805, more stable and reliable than 1117, but only supports 12V. So be aware if you need it otherwise we will automatically send the DC version and will also make changes at the terminals. If you need to heat the bed, it is recommended to use the terminal block. 3 hot bed heating output and temperature sensing, power interface supports DC and terminals. USB to serial port module using a dedicated serial chip to solve the Compact Edition Windows can not install the driver problem. Replace the A4988 with a better performing DRV8825 drive. product description Design highlights: 1. Can be directly connected to Ramps1.4, 2004LCD control panel and 12864LCD control panel. Excellent 7805 dedicated power chip, only supports 12V power input, solves the Mage2560 1117 chip serious heat problems. Circuit board using high-quality 4-layer panel production, especially thermal optimization. The use of TIs DRV8825 motor drive components, the performance better than the 4988 SOP package, cooling better default is 16, but can support 32 segments. Set all the features on the board to solve common problems such as the complex interface Ramps1.4 set.
