Foca Max is a USB to TTL serial converter board with maximum 5.5V2A output. For USB to TTL conversion, the Foca Max can be power supplied by USB only or USB together with external DC 8-26V, The USB and external DC power supplies are isolated by using a diode (SS34) to avoid the current backflowed between them.

Note: as for the Nextion HMI display size less than 4.3'', you can only use the USB for power supply, size large than 4.3'', a external DC 8-26V for power supply is recommended.
