Arduino 4x4 Driver Shield, 5A High-Side Chs., Chainable, DB25M US$10.95

Arduino 4x4 Driver Shield, 5A High-Side Chs., Chainable, DB25M

The 4x4 Driver Shield is designed to enable you to switch DC loads up to 5A at up to 30V with no heat-sinking. It is ideal for such applications as driving solenoids, relays, and small DC motors. It uses International Rectifier IPS6044 quad-channel fully protected high-side MOSFET switches, which include over-temp, over-current, and under-voltage protection. The high-side topology is safer in many applications than the more common low-side topology because a short to ground cannot energize the circuit while the switch is turned off. This shield also can be used to drive four unipolar stepper motors.

The board is built with generous traces to handle the current with minimal voltage loss and heating on the board. A pair of 74AHCT595 8-bit shift registers allow the control of sixteen high-current channels from only four Arduino pins using the shiftOut() function, and make it possible to daisy-chain as many as 25 boards off a single host, for a total of 400 high current channels.

4x4 Driver Shield Features

  • Arduino shield form factor compatible with all shield-compatible Arduino variants and clones
  • Sixteen 5A high-side driver channels
  • Shift register control allows daisy-chaining of up to 25 boards for a total of 400 channels
  • Uses only digital pins 7, 8, 11, and 13, leaving all serial, PWM, and analog input lines free
  • Mapped to the hardware SPI bus on the Arduino Uno, allowing high-speed data transfer
  • Inexpensive and robust DB25 male connector carries power and outputs
  • Four separate power supply circuits allow maximum application flexibility
  • Ships with loose connectors for end-user flexibility, including use with non-Arduino hosts
