TS100 Intelligent Shock Absorption Metal Robot Tank Car Chassis Obstacle Crossing Robot Kit

TS100 Intelligent Shock Absorption Metal Robot Tank Car Chassis Obstacle Crossing Robot Kit

Only Gold Chassis Car Kit can click ID: 1335202 to refer and buy. Introduction: A novel design has already come for the tank chassis, with beautiful shape, and full metal aluminum alloy structure. In this tank chassis, a space for the 9g servo is left for the ultrasonic sensor, and space for MG995 servo is also left to rotate the mechanical manipulator. What's more, UNO R3 and NodeMCU development boards are also designed to install. In addition, the metal panel can be used to install the wheeled car by install the 25mm and/or 37mm motor frames. Interesting, a LED light is installed to brighten the dark in the night. Under the help of the motor, the tank chassis can be smoothly turn left, right, circle, forward and backward, etc. Therefore, when you get the chassis, it can do many things for you, like getting the temperature and mobile monitor. Certainly, we have developed a series of car/tank chassis. Hoping you can choose your loved car chassis.

Geeetech StepStick DRV8825 Stepper Motor Driver Carrier - Black

Geeetech StepStick DRV8825 Stepper Motor Driver Carrier - Black

The DRV8825 stepper motor driver carrier 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 our 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, over-current and over-temperature protection, and six micro step 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).

Features:

1. Simple step and direction control interface;
2. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step;
3. Can interface directly with 3.3 V and 5 V systems;
4. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout;
5. Short-to-ground and shorted-load protection;
6. 4-layer, 2 oz copper PCB for improved heat dissipation;
7. Exposed solderable ground pad below the driver IC on the bottom of the PCB;
8. Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information);
9. 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;
10. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay);
11. 45 V maximum supply voltage;
12. Built-in regulator (no external logic voltage supply needed).
