Excellent article, thanks. At the risk of missing the forest for the trees, I wonder how much simpler things would have been if you had been slightly flexible on the 8-pin requirement. It seems as though having just a few more pins would have reduced the complexity of the project significantly while only marginally increasing the time it takes to solder.
- dmitrygr 2y agoIt would be no challenge at all then. And no fun. There are plenty much faster chips with USB built-in Hell, allwinner v3s is hand solderable and has built in RAM and will happily boot Linux natively Rp2350 would also be an excellent choice. It has a very good QSPI ram interface with cache built-in and usb support.
- RainyDayTmrw 2y agoHand-solderable might be relative. Certainly, QFNs and BGAs are more difficult. But I don't think the average hobbyist can solder QFPs, especially with an exposed underside pad. Heck, as a hobbyist, I don't think I'd trust myself to solder SOICs.
- dmitrygr 2y agoSoic8 is doable as your first soldering project. I tried this out on a few people successfully.
