Description: Highly integrated one board, to solve the Ramps1.4 combination interface cumbersome problem. Optimized layout routing and thermal design, the whole board performance is more stable. Large USB, more stable connection, more concise interface, wiring more convenient, more stable, longer life. On-board 4-channel A4988 16-step stepping motor driver ( Z-Axis motor interface ). PWM DC 3 outputs ( 1 channel high current, 3 channel medium current, 2 channel small current ). Mos tube with high performance and low on-resistance is used for driving, and the heat dissipation is better. Specification: Model Number: V1.0 Material?pcd Size(L x W x H): 10.00 x 9.50 x 2.00 cm / 3.94 x 3.74 x 0.79 inches ST power supply chip, support 12V - 24V power input to solve the Ramps voltage conversion chip fever problem. Can accept 24V input, the same system power can be reduced to 1/4 of the hot bed current, solve the hot-bed MOS tube heating problem effectively. Can use open source firmware Marlin, configuration and Ramps1.4 exactly the same, can directly replace Ramps1.4. Can be directly connected Ramps1.4, 2004LCD control panel and 12864LCD control panel ( remove the L-type adapter plate ). Package Includes: 1Piecex Controller Board
