Xiao STM32C5 has arrived!

Got the Seeed Studio XIAO STM32C5 as a part of the giveaway on Discord!

First thing that struck me is how small it actually is. It’s impressive they fit the STM32C5A3CG and a CAN transceiver into this size. The metal shielding on this XIAO looks like the biggest one yet! I haven’t seen a shield this large on other variants.

It has dual CAN FD, with one channel using an onboard transceiver, plus a 6-axis IMU with a heater, so I’m curious to see how that works in practice.

I’ll start with a basic blinky, then move to IMU logging. The 16 MB of flash should be more than enough for that. If anyone here has used this board already, any gotchas I should know about?
