Through hole Version?

[koombot]

Hi. I am trying to learn coding with microcontrollers (at the age of 40 something) and I've found this project thanks to some youtube videos. I love the idea it it looks like it would have helped me out several times, as well as being a good learning tool. The PCB design looks fantastic. I was wondering though would there be a significant loss in performance if I were to make a through hole version instead? I like to practice my soldering and enjoy making my own kit. Not that it is a major issue if it will cause problems, I'd just order the PCB if not, or rather 20 since it seems to be the same price. I'm sure some of the local schools will find them useful.

Thanks so much for providing this. The software looks phenomenal.

Hi. Being th or smd does not make a difference per se, but there are some caveats that you must take in consideration. First, the shifters do not come in any th package, only smd, and these are the best I have found in its class, other translators may yield different results with high speed signals and ref voltages. Second, if by "making my own kit" you are thinking on using a breadboard and wires... Don't, just don't, that will really hurt the signals integrity and relative delays. Even if the components are smd, soldering them are relatively easy, the only difficulty is in the capacitors and resistors and with KiCad you can change the footprints to something bigger like 0603. I have assembled the analyzers manually for a long time and it's really easy, just get a good flux and solder braid and it should not be a problem. Also, check the wiki, there is an explanation on how to use the pico in barebone mode (beware, the pico2 will get crazy used like this because of the gpio bug), if you only plan to check 3.3v signals then you don't need anything else but the pico, bridge gpio0 and gpio1 and that's it.

Thanks for the swift response. I'm currently working with esp32 mostly so the 3.3v will be fine to understand the software and how to use it. I'll need to think on a next step for whether to order it assembled or whether I get myself another fun project in making one with just the PCB.

TH would be useful for the PI. It would make it possible to use a socket for testing and swapping PIs. SMT sockets are hard to find and expensive.

I mean a PI with headers.
