Basys MX3: PIC32MX Trainer Board for Embedded Systems Courses

Description

The Basys MX3 is a development platform for the Microchip PIC microcontroller (PIC32MX370). With an exhaustive set of peripherals, users can create a wide range of embedded systems applications. The board also provides an easy and cost-effective introduction to the PIC32 microcontroller and  MPLAB® X Integrated Development Environment (IDE). A complete set of software libraries are included, allowing users to make simple function calls to all onboard peripherals, greatly simplifying the development process. With the on-board debug headers and USB programmer/debugger, users can debug their designs directly from MPLAB® X Integrated Development Environment, or scope digital and analog signals through Analog Discovery 2 or Digital Discovery.

Accompanied by free and open-source coursework, including 7 in-depth teaching units and 15 complete labs, the Basys MX3 is also a versatile MCU trainer board ideal for teaching introductory embedded systems courses. It covers topics from toggling LED’s motor control to digital signal processing. The coursework is designed for sophomore/junior level embedded systems courses.
