  Amazing to see the tight integration of everything. microsd instead of nand chips, integrated inductors inside chips, one big heatsink, standard usb power benefitting from scale instead of expensive in-chassis DC-DC, standard android OS...  It's built down to a cost, but I'd argue that a lot of these choices are preferred over more custom solutions. E.g. industry-standard isolated USB-C PSU isn't going to easily fail as it already has millions of units in the field.

  &quot;small sparrow&quot; is a reference of a Chinese saying that goes like “麻雀虽小五脏俱全”, meaning &quot;The sparrow may be small, but It is fully-equipped&quot;.<br>It&apos;s really a nice touch!

  The reason they likely populated the bypass caps and termination resistors is likely to prevent the traces turning into antennae and injecting noise into the unused inputs. Basically the same as tying unused logic ic inputs to either power of ground.

  Re. populating all the passives - bear in mind that small passives and larger chips are typically placed on different machines, so may also be a factor in simplifying their production process

  @<a href="https://www.youtube.com/watch?v=KQF4UzLPpr0&amp;t=720">12:00</a> will be the same mould, it will have an interchangeable insert to block that section off for that model. The moulds are actually fairly complex with under cuts and side wedges along with small features.

  SD card is interesting - could simply be that it&apos;s cheaper than an emmc card, and surprising there doesn&apos;t appear to be an emmc footprint. Suppose it makes it easy for them to up-size it easily in future, but it also seems to scream &quot;hack me&quot;

  Dave - we need a DHO800 vs Siglent SDS800X HD comparison !

  You can get right angle USB-C cables for working &nbsp;flat

  MicroSD also means not having to do any in-circuit programming on the final board - could save on production time &amp; test fixturing, as copying to onboard emmc could take significant time. They probably also have a &quot;special&quot; version for production test

  I cannot justify buying another scope, but I want it.

  That &quot;Joshua&quot; login suggestion was awesome! &nbsp; Just watched Wargames the other day!
