Evaluation tools

Postby sandiesharples » Tue Jan 22, 2013 4:41 pm

Do engineers actually bother with evaluation boards and development boards to try out a new radio module? They are an expensive start to the design if they are specifically for testing the one module type. Is it worth it?

Absolutely!

Here we have three radio module (GSM) dev boards in use - plus (at least) one microcontroller dev board:

The price of a devboard is trivial relative to the cost of time to debug design flaws in untried boards!

It is invaluable to have a "known-good" reference!

Thanks for the reply - its what I had hoped to hear and everything you said makes sense to me. It is a significant initial cost but could save time and money in the long run.
It still maybe the case, that due to budgets being more closely monitored during recent years, more research is done prior to buying samples and kits and the days of "I will have one of those and one of those" have gone for now. There is certainly a huge range of wireless modules in the low power area now - lots of start ups and overseas contributions as well as the long standing names - some fantastic and some not so good. It must be hard to know where to start!

And if you have the old RS232 development board you can still use these with the latest ERA modules and easyRadio Companion software. The latest eRA transmitter has an extra pin (SDO) but you can still get feedback from this pin by connecting that pin to the TRS sockets.
