Re: Micro Pi

Thank you for suggestions of other chips,
but one of the main requirements is code compatibility.
Having written and proven the software on a RasPi, I would wish Raspbian and my code to run (ideally) unchanged on a Micro-Pi.
Too much to hope for?

Re: Micro Pi

Thanks Moderator, Yes I am aware of the model A capabilities, but the critical factor is size (max 15x25mm) in order to fit inside the ATrack AX5. I was hoping that other RasPi users might want something similar, perhaps in the robotics area. My application is currently running in the car on a model...

Re: Micro Pi

Thanks for your helpful ideas. I have no plan to monitor speeding offences, the unit is designed to have absolutely no user interface, in order to avoid distracting the driver, and hence allowing easier 'e-marking'. I know that this request is outside the Educational Purposes of the RasPi, but was r...

Re: Micro Pi

Tamper resistance would be a combination of sealing the unit - it simply plugs into the vehicles OBD-II socket below the steering wheel, and software. All GPS tracking devices can be defeated - the trick is to make the driver appreciate the functionality supplied. Power is indeed plentiful in a car,...

Re: Micro Pi

The use case for my application in the Young Drivers Insurance market is to monitor and report on the class of roads driven, distance and time of day to determine the Risk and hence the Premium.

Micro Pi

Apologies I cannot find the 'Suggestions' topic, so writing it here. What I need, and I hope others would benefit, is a really cut-down version of the Raspberry Pi, to use as a headless, code compatible 'Application Processor': No HDMI, No RCA Video, No Sound, No GPIO, No Ethernet, One USB for conne...

Successfully installed cpanm on Raspberry Pi using clean install of raspbian,
but 'sudo cpanm XML::Parser'
