I haven’t developed anything with Sierra’s products however I have experience with PCB design and programming. I am about to start a project that will practically be a telemetry application with low data rate requirements. Among others, I am considering Sierra’s products, and I will most likely use either Q2686 or Q2687.
However, I am not sure how to start developing and testing my idea mainly because due to the high cost of the available development boards (~$600).
If the project goes well at the very end I will need to design my own PCB in order to embed it in my application. Considering this can somebody answer the following question and give any pointers on how to get started:
If I don’t buy the available development boards is there some more other affordable programmer? I will need to do a lot of in-system-programming (ISP) when I finally design the PCB and start developing my application. I would be willing to build my own programmer, but is there some available design/drivers on line? For example, is it possible to program a Q2686 in system via the SPI bus, and if yes, can I use a third-party programmer that works with the SPI bus. (For people familiar with AVR devices: I have an STK 500 board that can be used for ISP through the SPI bus. Would it be possible to use the STK 500 to program a Q2686?)
Can I use the available boards (e.g. AirPrime Q26 kit) as an ISP programmer for a Q2686 or Q2687?
Do you have any good references how to go about designing my first board?
Thanks a lot,
