  • Description
A complete starter kit and development system for the C8051F320 microcontroller

Overview

A complete starter kit and development system for the C8051F320 microcontroller. It is designed to give designers a quick start to develop code on the device.

This development system contains a main development board with the C8051F320 chip in LQFP32 package, and an additional expansion board with various peripheral devices.

The BUS-A & BUS-B headers located on both boards should be used to connect the two boards via 10-pin cables, which are delivered with the product. As shown in the figure right.
