Mini-Review: Solder Party's RP2350 boards

Solder Party is a Swedish company that has some peculiar boards. For the RP2350 (and RP2040), they have stamp boards, which contain the microcontroller, and carrier boards, where the stamps are connected and provide power and input/output connectors. One detail that will bother many people is that the pin spacing on the stamp boards is 2 mm instead of the more traditional 0.1" (2.54 mm). SolderParty sells connectors with this spacing. Although some carriers have RP2040 in their names, all models work with RP2040 and RP2350 stamps. I purchased both stamp models with RP2350 and the three carrier models. Here are some comments on them. The RP2350 Stamp XL installed into the RP2xxx Stamp Carrier XL
