Hello,
I am currently experimenting with your VOXL2 product. I'd like to attach External Flight Core to the VOXL2, but I'm facing a challenge. Among the parts I've received, only one of either MDK-M0078-2-00 or MDK-M0151-1-00 can be attached to the VOXL2. However, I need two UART ports: one for Wi-Fi and another for connecting the external Flight Core. Do you have any adapter that can accommodate both? Otherwise, how can I use the VOXL2 with an external Flight Core and Wi-Fi simultaneously?

@황대현 Please read further down in the document where DSP UART is discussed https://docs.modalai.com/voxl2-external-flight-controller/#dsp-uart-to-flight-core-v2
