A look at the EX-F34x-Q48 Development Board

In this article, we look at another development board option that we purchased for 8051 development. This time it is a EX-F34x-Q48 from waveshare and it is designed to support the C8051F340

This is what this board looks like




Powered from the mini USB port or 5V DC jack, configured via an onboard switch

There is a jumper for selecting on board 12M crystal or custom crystal mounted via the socket
All the C8051F340 I/O pins are accessible on the expansion connectors

The board comes with a CD with software, drivers, and examples. There is a pdf schematic and there are C examples for Silabs IDE and Keil


Again this board worked with the following low-cost debugger

The U-EC6 is a C8051F MCU USB interface debugger that can be used for the MCU simulation, debugging, download, encryption, and support for C8051F Full range of Microcontrollers.
Fully compatible with the USB Debug Adapter Silabs and EC3 / EC5 / EC6 debugger.
