Geekcreit® 3D Printer A4988 Reprap Stepper Motor Driver Module (3D2 red stepper driver)
Description:

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 modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed 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.

In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing.

A4988 surface mount QFN package (ES), a size of 5 mm × 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating.

Features:

Simple step and direction control interface
Short-to-ground and shorted-load protection
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
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 to achieve higher step rates

Package includeds:

1 x Step motor driver module

LilyPad Buzzer module (T1 wearable buzzer)

 This is a small buzzer for the LilyPad system. Use 2 I/O pins on the LilyPad main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud.

Please note: This is an inductive buzzer meaning that is will act as a short to ground if you are not actively driving it. We recommend you put both I/O pins to low (0V) when the buzzer is not used. Also, it's come to our attention that washing these buzzers will damage them. Until we've figured out a solution to this, avoid washing any portion of your project that contains one of these buzzers.

LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available.

Description:

The WCS1800 Hall Current sensor has two functions

  • current detection
  • over current protection (can be preset from 0.5A to 35.0A)

Features:

Operating voltage: DC 5V
Current detection range: DC +-35A, AC 25A
Linearity: K=60mV/A
Limit current range: 0.5A to 35A(for on/off value output)
Over current signal indicator LED
Sampling current conversion analog voltage signal output and it can connect ADC; TTL level signal output and it can connect MCU IO port control
Board size 37mm x 31mm
Working temperature: 25 to 85C

Interface



VCC: power positive
DOUT: TLL high/low level signal output
GND: power negative
AOUT: sampling current signal conversion voltage output port

Analog voltage signal output (AOUT)

Relationship between detection current and analog signal output is shown below:

Analog signal output: V0=Vcc*0.5±la*K (la is actual current through current detection pin, and K is linearity)

Eg: Input currentis 1A, Vcc=5V and WS1800 linearity is 60mV/A
  1. When the current flows in from positive direction: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V
  2. When the current flows in from negative direction: V0=Vcc*0.5-la*K, V0=(2.5-0.06)V=2.44V
  3. If it is an AC signal: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V

The above are ideal values. There might be some precision errors.

On/Off output(DOUT)

  1. Make sure the current flows in from the positive direction. Adjust to the desired current warning level.
  2. LED will be on when current is below the setting and DOUT will be low.
  3. When the detected current is higher than your setting, the LED will turn off and the DOUT pin will go high.
