MG90S Mini Digital 180 Degree Servo 2.2kg

The Towerpro MG90S Mini Digital Servo is 180° rotation servo. It is a Digital Servo Motor which receives and processes PWM signal faster and better. It equips sophisticated internal circuitry that provides good torque, holding power, and faster updates in response to external forces.

The good optimized performance and reliability of our servos have made them the favorite choice of many RC hobbyists.

They are packed within a tight sturdy plastic case which makes them water and dust resistant which is a very useful feature in RC planes, Boats, and RC Monster Trucks etc. It equips 3-wire JR servo plug which is compatible with Futaba connectors too.

The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.

The module has a pinout and interface that are nearly identical to those of the A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

Note: We are supplying two DRV8825 Drivers as DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Good Quality and DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Normal Quality. The difference between them is, the good quality DRV8825 has more number of PCB layers and it features the connecting pins which are of gold plated as compared to other. (refer to above image)

Using the Driver

Features :

1. Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
2. Simple step and direction control interface
3. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
4. Adjustable current control lets you set the maximum current output with a potentiometer. Hence lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
6. 45 V maximum supply voltage
7. Built-in regulator (no external logic voltage supply needed)
8. Can interface directly with 3.3 V and 5 V systems
9. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
10. Short-to-ground and shorted-load protection
11. 4-layer, 2 oz copper PCB for improved heat dissipation
12. Exposed solderable ground pad below the driver IC on the bottom of the PCB

Package Includes :

1 x DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Good Quality.

The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with built-in converter, easy to operate. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

A4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988.

There are no phase sequence tables, the high-frequency control interface programming etc. The application of A4988 interface is very suitable for a complex microprocessor is not available or overload. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increased step accuracy, and reduced power consumption.

Provide internal synchronous rectification contr

ol circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Don’t need special power-up sequencing. A4988 uses surface mount QFN package (ES), the size is 5 mm × 5 mm, nominal overall package height is 0.90 mm, with an exposed thermal pad to enhance the heat dissipation function.

Features :

1. Automatic current decay mode detection/choice.
2. Mixed with slow current decay mode.
3. The low power dissipation of synchronous rectifier.
4. Internal UVLO(ultra voltage lockout).
5. Crossover current protection.
6. Thermal shutdown circuit.
7. Ground fault protection.
8. Loading and short circuit protection.
9. The optional five-step mode: full, 1/2, 1/4, 1/8 and 1/16.

Package Includes :

1 x A4988 Stepper Motor Driver- Normal quality.

1 x Heat sink.
