The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to a max 2A/phase. It is based on the Allegro A4988 stepper driver chip. It’s the next version of the popular Easy Driver board.
The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital...
This is the breakout board for the thumb joystick. Pins are broken out to a 0.1" header and includes 4 mounting holes in the corners.
This version of the kit has received a complete overhaul! Check out the Kit Includes section below for a complete list of what is included in this kit to find out what has changed.
Note: When using this board in extreme high-demand applications it may be necessary to improve thermal performance with a heat-sink or fan and to solder the wires directly to the board instead of using a screw terminal (in addition to the myriad other complications present in a high-current system) However, when using the board at currents up to 6A the...
The RedBot comes pre-programmed with the Optiboot (Uno) bootloader. By simply connecting a USB mini-B cable, you can program it in the Arduino IDE using our example code, or your own. The optional add-on sensors attach to the main board via 6-pin headers or jumper cables to increase capabilities.
This electronic speed controller offers a battery eliminator circuit (BEC) provides 5V and 100mA to the receiver so no extra receiver battery is required.
The on-line MicroView SIK Digital Guide (in the Documents tab) contains step by step instructions of how to connect each circuit with the included parts. Full example code is provided and explained and even includes troubleshooting tips if something goes wrong.
STMicro’s L6470 is a 3A, 8–45V bipolar stepper motor driver. It has built-in overcurrent detection, undervoltage detection, overtemperature detection, stall detection, a 5-bit ADC, and a switch input that can be used for either user jog control or as a hard stop function.
The Spectacle Motion Board makes it easy to add movement to your Spectacle projects. Each Motion Board can control up to five servo motors, regardless of whether they are standard or continuous rotation type.
The SparkFun Serial Controlled Motor Driver (SCMD) is a DC motor driver that’s been designed to drive small DC motors with ease. The SCMD is designed to emulate a typical register-based device in operation. It can be commanded by UART, I
The heart of the Servo Trigger is an Atmel ATTiny84 microcontroller, running a small program that implements the servo control features we are discussing here.
The SparkFun Continuous Rotation (CR) Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state, the CR Servo Trigger is able to tell an attached servo motor to move from position A to position B.
We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on the motor voltage input and a pullup on the "standby" enable pin.
With the PWM pin held low, both motor outputs will be held low (a brake operation). With PWM high, the motor outputs will be driven according to the DIR input.
The extremely accurate, high-resolution servo pulses have a jitter of less than 200 ns, making this servo controller well suited for high-precision animatronics, and built-in speed and acceleration control make it easy to achieve smooth, seamless movements without requiring the control source to constantly compute and stream intermediate position updates...
Logic supply voltage (VCC) can be in the range of 2.7–5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC. The output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse).
It is ideal for robotic applications and well suited for connection to a microcontroller requiring just a couple of control lines per motor. It can also be interfaced with simple manual switches, TTL logic gates, relays, etc.
