Allwinner R8 in CHIP: now easier to solder

fustini

I was excited to see the final production design of the CHIP by Next Thing Co is now using a TQFP package of the Allwinner R8 processor module:

https://www.kickstarter.com/projects/1598272670/chip-the-worlds-first-9-computer/posts/1428989

We've made a change from the smaller R8m (our Alpha C.H.I.P. processor) to the larger R8, which are functionally identical. Because of sourcing complications and repackaging costs for the R8m, we've chosen to move forward with the R8 to remain on time and on budget.

 

Here's what the Alpha CHIP board looked like with the smaller R8 package:

A big reason that I am a fan of CHIP is that it is Open Source Hardware.  I think the larger R8 package will make it easier for people to design and assemble derivatives.

 

Finally, it's great to see that Linux kernel developer Maxime Ripard of Free Electrons is visitng Next Thing Co.  I'm very encouraged by their progress in getting CHIP supported by the mainline Linux kernel.

https://www.kickstarter.com/projects/1598272670/chip-the-worlds-first-9-computer/posts/1412368

Building an operating system for C.H.I.P. requires some heavy duty driver work. Maxime Ripard from Free Electrons abandoned the French countryside and joined us in sunny Oakland, CA to make sure we’re on-time and feature rich.

 

cheers,

drew

    CHIP is Open Source Hardware as the Schematics, Board Layout and Bill of Material are released under an Open Source license . Next Thing Co has written about their approach to Open Source development:…

    Glad to see them using TQFP.  I really mistrust BGAs.

     

    One of my favorite chips was the IBM PPC401GF, a 32-bit PowerPC in an 80-pin PQFP with multiplexed address/data bus.  Delightful little easy-to-probe package.  It worked really well with a 32-bit synchronous SRAM chip.

     

    IBM had a nice set of embedded PowerPC parts with excellent documentation. They sold the product line to AMCC (now Applied Micro) where they languished.  Too bad -- I really prefer the PowerPC instruction set to x86 or ARM.
