Re: What would be the next step up from CM3?

You appear to have not undertaken much research, which is a shame if you intend to manufacture a product. There are open source Allwinner SoC based SBCs available, such as: https://www.olimex.com/Products/OLinuXino/open-source-hardware https://www.olimex.com/Products/SOM/ Indeed I haven't undertake...

Re: What would be the next step up from CM3?

Something just realised, that I could build my own CM3 and have that flush with custom PCB. However does anyone know the components used in this? I already know it uses the BROADCOM BCM2837, Samsung Electronics 701 KLM4G1FEPD S554F021 & the ELPIDA B8132B4PB-8D-F 17110R61500. At which point I'd advi...

Re: What would be the next step up from CM3?

That could be a nice possibility.

I will look into this at a later date as I noticed for what I want, I would have to order 1000 units instead of creating 1 for prototype.

Re: Pi Zero long camera cable bond?

Sorry to resurrect a dead thread, but if you're still looking for a solution then it might be worth you time looking on Aliexpress. I found the 22-pin 0.5mm pitch ribbon cables that are required to connect to the RPI Zero camera connector. If you make yourself a custom PCB and use this 22 pin connec...

Re: Where can I find a ribbon cable that I can use to extend the Pi Zero and Fish eye lens?

I would like to correct my previous post I ordered the above cables and then realised they were too big in size. This is because the Pi zero camera takes in a 22 pin with 0.5mm pitch and not the 1.0mm pitch I had previously posted up. There are 2 options same side & reverse direction. Same side mean...

Re: What would be the next step up from CM3?

CM3 is the current top of range CM board. No-one else I know of make CM compatible boards with more processing power, or smaller footprint. Sounds like you need to consider designing your own PCB, choosing an SoC that matches your requirements. Note, you cannot buy the CM3 SoC unless you are buying...

Re: Where can I find a ribbon cable that I can use to extend the Pi Zero and Fish eye lens?

I do not think the Raspberry Pi 2/3 cable will fit the Raspberry Pi Zero. The Zero's camera port appears to be narrower then the Pi 2/3 port.

Re: Where can I find a ribbon cable that I can use to extend the Pi Zero and Fish eye lens?

Small update did some more digging about and changed keywords on google and I found the cable. As we already know the Pi Zero Camera port connector is a 22 pin connector. All I had to do was search up 22 pin ribbon cable and it came with a bunch and I found one for amazon. So pasting here for future...

Re: Cm3 - Battery charge notifications what pins do I require?

The documentation indicates LBO is "Low Battery Output. By default it is pulled high to BAT but when the charger detects a low voltage (under 3.2V) the pin will drop down to 0V". That same documentation describes "VS" as "When there is 5V coming in from the micro-B USB power plug, this pin will hav...
