Version with Qwiic? #2

Open samuk opened 7 months ago

samuk commented 7 months ago

I'd be interested in a version of this board that included a Qwiic connector next to the Grove. Would you be interested in editing your project to add this?

Of course I can fork and try to add it myself, but it may be possible to keep the versions together?

Do you have any plans to sell the boards on Tindie or whatever?

I could edit my project. Would you need Qwiic connector as add on, or as replacement to Grove ?

I could sell it on somewhere, how many would you need ?

Keep in mind that it takes a while to get them made and I also need to manually add camera connectors and UART/I2C connectors.

I am powering this board with RPI power supply sold by Raspberry PI. I might look into some other chargers as well, but that complicates the design.

I don't personally need the Grove, but might be good if there was space for both. Adaptor cables are a possibility too.

I'm just evaluating the available open hardware CM4 carriers for a project, I guess I'd need 5-10 if I did decide this was the one to go with.

It looks like JLPCB could do the camera connectors? they can also do Qwiic (SMD) so maybe you could leave the Grove unpopulated if JLPCB can't do it? Those that want it could do TH soldering for that one?

Another one to consider might be to get https://www.makerfabs.com/ to fab up some boards, they offer a service where they will warehouse them in China for you and then dropship Tindie orders.

I will have a look if I can easily fit Qwiic connector. Please give me a few days, I am quite busy at work these days as this project is just my hobby.

You are correct regarding the camera connectors, JLCPCB has them again on the stock, that was not the case about 6 months ago.

I will also have a look at makerfabs.com. Thanks for the suggestion.

GPIO3 is SCL and GPIO2 is SDA. I have added Qwiic for I2C, I guess UART is not needed(or maybe) ? I dont have any Qwiic connectors at home, so I assume that I have found the correct connector (PRT-14417) and pinout is from the Sparkfun website.
