Product Information

A4988
Product details
A4988 is a complete microstepping motor driver with built-in translator for easy operation.This product is available in full, half,1/4,1/8 and 1/16 step modesoperate
bipolar stepper motors,output drive capacity ofup to 35 V and ±2A.A4988 includes a fixed off-time current regulator, the regulator in slow ormixed decay modes.A4988 converter is the key to the easy implementation.As long as the “step” input inputting one pulse drives the motor one microstep.There are no phase sequence tables, high frequency control lines, or complex interfaces to program.A4988 interface is very suitable for complex microprocessoris unavailable or is overburdened.

In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device isinitially set to a fixed downtime in some fast decay, then the rest of the slow decaydowntime. Mixed decay current control scheme results in reduced audible motornoise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-widthmodulation (PWM) operation power consumption.Internal circuit protectionincludes: thermal shutdown with hysteresis,undervoltage lockout (UVLO), andcrossover-current protection. Special power sequencing.We Are The Distributor Of TZT Brand In Hong Kong, China A4988 surface mount QFN package (ES), a size of 5 mm ×5 mm, nominaloverall package height of 0.90 mm, with an exposed pad for enhanced thermaldissipation.This package is Pb(suffix-T), with 100% matte tinleadframe plating.

UNO R3 SMD CH340G + Cable
Introduce
UNO is a Simple ilo platform based on open source code, and it has thecharacteristics of easy to understand using Processing/Wiring developmentenvironment similar to Java and C language.Let you quickly use uno to makeinteresting things. Uno can be used with some electronic components such asLED lights, buzzers, keys, photoresistors and so on.The uno developmentenvironment interface is based on the open source
principleallowing you todownload,use and develop more amazing interactive works for free.Open thecircuit diagram of the original design, develop software interface for freedownload, but also according to the needs of their own modification,downloadprocedures are simple and convenient. It can simply use sensors and variouselectronic components to connect (e.g.LED lights, buzzers, keys,photoresistors,etc.) to make a variety of interesting works. Using high-speedmicroprocessor controller(ATMEGA328), the development of operationinterface and environment is very simple and easy to understand, which isvery suitable for beginners to learn.
