Nextion Foca Max USB to TTL komunikacijos ir 5V2A maitinimo modulis

Foca Max is a USB to TTL serial converter board with 5.5V2A output. it integrates a high power and energy-efficient DC-DC chip of TPS54331 for a wide voltage input with small voltage ripple. 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 use the USB power supply, but for larger than 4.3” displays, a external DC 8-26V for power supply is recommended.
