To complete projects in the book "Embedded Computing and Mechatronics with the PIC32 Microcontroller" (Lynch/Marchuk/Elwin, Newnes 2015), we recommend the following "kits."

Minimum Electronics Kit

We recommend this set of parts for simple interfacing with the NU32, as described throughout the book. These are available from many vendors; below are some examples where they can be purchased.

The Brushed DC Motor Control Kit

These items are needed to complete the projects associated with a brushed DC motor.

  • a brushed DC motor with no gearhead that draws less than 1 A at stall when powered by 6 V, with an incremental encoder (as many counts per revolution as possible, preferably at least hundreds). No gearhead makes it easier to characterize the motor without having to worry about high friction in the gearhead. You can search surplus and other sites for such motors (e.g., aliexpress.com, ebay.com, etc.)
  • a 6 V battery pack to power the motor (6 V is not critical; other voltages are possible, provided the motor does not draw much more than about 1 A at stall)
  • 20 ohm 5 W power resistor
  • the motor control board, consisting of a TI DRV8835 H-bridge chip, the MAX9918 current-sense amplifier, and a PICxxx? encoder counter chip that speaks SPI
  • a motor mount to mount the motor securely to the table
  • an inertia bar to attach to the motor to vary its load

Useful Optional Components

The following equipment is used in code samples in the book.

Other Components Referenced or Used in the Book

These components, referenced in the book, can be sourced from various suppliers:
