The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.

The translator is the key to the easy implementation of the A4988. Simply inputting one pulse on the STEP input drives the motor one microstep.

This product is a breakout board for Allegro¡¯s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product.

The power supply and hot bed use 30A high-current terminal block, to avoid the situation of burning terminals to a greater extent

Added a reset expansion interface, convenient for users to extend the reset button, X, Y, Z, E0, E1 all use parallel dual motor interface, so that the board is suitable for more models

Design of plate pin socket can be easily replaced or removed for future design, Changed the silk screen, making the wiring clear at a glance. Using a combination of colored pin headers and mothers, effectively distinguishing each functional interface, both beautiful and practical

Recommended Operating Voltage: 3V~12VDC (recommended operating voltage of about 6 to 8V).Voltage:6V; No-Load Current:≤200mA; No-Load Speed:200±10% rpm. Voltage:3V; No-Load Current:≤150mA; No-Load Speed:90±10% rpm.

3V-170mA; 115RPM, 0.7KGf.cm torque, With EMC, strong magnetic, it has an anti-interference ability.

Use For With EMC, strong magnetic, it has an anti-interference ability.Widely used in electric toy products such as robots, four-wheel-drive vehicles and unmanned aerial vehicles. etc.

Easy to use : each jumper has stripped ends and preformed right-angled leads for easy insertion into your breadboard ,all the colored jumper wire are pre-stripped and preformed right-angled, easy to insert it into breadboard.

Wide Application : designed to work well with any breadboards or anywhere jumper wires are needed, perfect for breadboard projects these breadboards wires are ideal for use with any breadboard, prototyping, prototype circuits, LED strip, test circuits and etc.

Package includes : contains 840 pieces U shape preformed breadboard jumper wire kit, 14 lengths, 60 pieces per size,Note: the breadboard wire is a little soft that convenient for changing its shape to do connect test; if you find that it can't be inserted, please check whether the cable in the pin hole of a breadboard is in good condition or not.come with a free plastic box, keep your jumper wire kit organized, convenient for store and fetch.

Support a variety of stepper drivers: A4988,DRV8825,TMC2208 and TMC2100, and available to work with LCD2004,LCD12864,MKS TFT24/28/32/35 & Available to connect external large stepp drivers, A4988 driver board widely used in 3D printers and small CNC machines.

Support functions: Non-trace resumption after power off, run out filament ,and auto shut down, XTZ axis with different color terminal controls the motors and end stop,which is convenient to wire.Use high-quality 4 layer PCB&Use special power chip.Retail Servos,AUX-1 and AUX-2 interface of Ramps1.4 provide three 5V output and three 12V output interfaces.

Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step.Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage toachieve higher step rates.Use the configuration file to set the driving current mode, avoid manual adjustment of the current to cause the burned drive, convenient, safe and reliable.

Suitable - Works on 1-8 Cell Lipo Batteries with JST-XH Balance Lead Compatible with 1-8s Lipo/Li-ion/LiMn/Li-fe RC battery, the pin space is about 3 mm (0.12 inch) straight pin.

Low Voltage Alarm - Extra Loud Alarm ,When the voltage is lower than the set value, the buzzer will ring and the red LED light will flash. The factory default is 3.3v. Press the button to change the voltage setting value and save it automatically.

LED Display Mode - Battery cell voltages, total voltages, lowest cell voltage, remaining battery capacity. Cycle display battery working status, protect battery from over-charging or over-discharging.

Design: The battery power detector comes with protective shell, dustproof waterproof surface; input reverse connection protection.

Alarm:If low voltage, red indicator flashes and buzzer alarms. red wire for the positive, black wire for the negative.

Application: you can use the battery monitor as battery capacity tester, battery voltage meter, this multimeter can be used as battery voltage tester meter, battery capacity detector and temperature indicator panel for club car, marine, RV, boat, and portable equipment.etc.
