This breakout board for Allegro's A4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). 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). This board ships with 0.1? male header pins included but soldered in.
Simple step and direction control interface
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
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
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
Short-to-ground and shorted-load protection
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
This 12-inch (30-cm) cable has three 26 AWG wires with a 3-pin female JST PH-style connector that matches the connector on Sharp analog distance sensors that have 3 pins. The other ends of the wires are unterminated; they can be cut to length to match your application. The wire color scheme matches the Sharp distance sensor pinout: red for power, black...
DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. Compared to the DS1302 solution, the DS3231 has many advantages, it function with a VCC ranging from 2.3V to 5.5V and has a battery backup. Unlike the DS1307, the DS3231 also has an integrated crystal (so no...
This is the HP QDSP-6064 bubble display, a tiny, 4-digit, 7-segment numerical indicator. THis little guy is perfect if you need some user feedback from your system, but do rsquo;t want to fiddle with LCDs or other display options. The Bubble Display comes in an easy-to-use 12-pin DIP package and can be used in breadboards, protoboards, or PCBs.
