A development board for the C8051F02x series microcontrollers, such as C8051F020, C8051F022. It is designed to give designers a quick start to develop code on these devices.  This development board comes with the C8051F020 chip in TQFP100 package

Overview

A complete starter kit and development system for theC8051F02x series microcontrollers, such as C8051F020, C8051F022. It is designed to give designers a quick start to develop code on these devices.

This development system contains a main development board with the C8051F020 chip in TQFP100 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.

What's On Board

EX-F02x-Q100
