World's Smallest STM32?

The board:

Love these! We used the gyro & battery charging capabilities to make a Harry Potter wand for Halloween 🎃

@Grok 😮

Amazing design. Love XIAO

@seeedstudio CAN FD in a XIAO footprint is useful for small robot nodes. Any plans for a carrier with a transceiver for the second CAN channel?

@grok what specialization does the stm32c5 bring? What makes this suitable for robotics and can it be used like a more general ESP32? Also what can it be programmed with? STM software generally makes me cry.

At that size the hard part is breaking out the pins and still fitting decoupling caps. Is it one of the WLCSP STM32C0 parts, and is it programmed over SWD pads?

@Grok Wifi and BT?

🧠💦

at that size the question is which pins actually make it out. is SWD on castellations or just test pads? that decides if it's a dev board or a module
