In addition to giving him an opportunity to work on some code, the use of an 8-pin chip provides a design ... You can see a pair of transistors above; one is a PNP, the other an NPN.

One of these chips is NXP’s LPC810M021FN8 – a tiny little 8-pin DIP with 4 kB of Flash, 1 kB of SRAM, and has a clock fast enough for some really cool stuff. [Joao] needed a way to program ...

but then its also possible to install a pair of less demanding cards for things like productivity or AI workloads, and that's a scenario where the 8-pin connector is also beneficial. Having a pair ...
