Hi guys, I recently discovered you, and I’m very excited with what will come soon in Blues.

I have a pretty basic question. Are the blue pill (STM32F103 arquitecture) or the black pill (STM32F411 arquitecture) compatible with the Notecard Outboard Firmware Update feature?

Hi @kyellow and welcome to the Blues community!

We do support both of those architectures, however it’s not a trivial task as neither board directly exposes the required pins. You’ll need to wire your hosts as [documented here](https://dev.blues.io/guides-and-tutorials/notecard-guides/notecard-outboard-firmware-update/#required-wiring). I would recommend using the [Swan](https://shop.blues.com/collections/swan/products/swan) as it’s a more capable STM32 host and exposes the necessary pins.

Thanks,  
Rob
