which appears to me to be a well reasoned explanation of why the Raspberry Pi foundation might want to consider a model A with more memory or equivalently a Zero with a camera connector. It seems worth discussing the robotics and mobile computing projects that could benefit from a small form factor, at least 512mb of RAM and a camera. I'm posting a new thread focusing on what projects would be enabled by such hardware because the previous thread was closed, apparently due to a forum policy that prohibits speculation by third parties about when new hardware might be announced. My understanding is that such speculation was getting picked up by webcrawlers and misinterpreted as authoritative due to the forum sharing the same domain name as the official website.doughadfield wrote: There's a clear anomaly in the current line-up of RPi products (Pi2, A+, Zero) in that the A+ is still stuck on 256MB memory. However it's the ideal platform (in every other way) for camera projects. For all other "Model A" uses, obviously the Zero is the best choice (once it's back in stock!!) - however, it lacks the critical camera connector. Therefore, for embedded camera-based projects, only the A+ remains in the lineup. However most camera projects require at least 128MB GPU memory, leaving too little for processing such as motion capture, etc.
At any rate, I built a Raspberry Pi controlled toy car with a Model B some time ago. The GPIO was wired to the existing H-bridges in the car to control the motors with almost no additional hardware or cost, however, one of the larger toy cars was needed in order to fit everything on top of it. This increased expense and meant more floor space was needed to operate the car. The floor space was actually the biggest difficulty because the larger car really only works well in the school cafeteria after all chairs and tables are removed. A Pi the size of the Zero but with a camera connector would allow use of smaller toy cars and much smaller rooms.
I suspect balloon projects would also benefit from smaller and more powerful hardware with a camera connector, but I don't have any experience with balloons.
