Waveshare EX-F320 C8051F320 8051 Development Board

Artikelnummer: WS0801S

Hersteller Artikel Nr.: EX-F320 Standard

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.
