Foca Max USB TTL converter for Nextion displays

Foca Max USB to TTL converter, designed for use with Nextion displays. With an external 8-26V DC power input, Foca Max provides a stable power source and convenient USB to TTL communication for all series and sizes of Nextion HMI displays. Foca Max is a serial USB to TTL converter with a maximum output of 5.5V 2A. For USB to TTL conversion, Foca Max can be powered by USB only or by USB together with an external 8-26V DC power supply. The USB and external DC power supplies are isolated by a diode (SS34) to avoid current flow between them. Note: For Nextion HMI displays smaller than 4.3'', USB can only be used for power supply; for sizes larger than 4.3'', an external 8-26V DC power supply is recommended.
