- Nextion Foca Max 5V2A Output USB To TTL Serial Converter Board
- Equipped with a high-performance SILABS CP2102 chip
- Features a high-power, energy-efficient DC converter chip TPS54331
- Can be powered solely by USB or with an external DC 8-26V power supply
- Designed with LED indicators for input/output power and TX/RX communication
The Nextion Foca Max 5V2A Output USB To TTL Serial Converter Board is a high-performance converter board that facilitates USB to TTL serial conversion with a maximum output of 5.5V2A. The board can be powered solely by USB or in conjunction with an external DC ranging from 8-26V. To prevent current backflow between the USB and external DC power supplies, a diode (SS34) is utilized for isolation.
The board is equipped with a SILABS CP2102 chip, which allows for a maximum baud rate of 2 Mbps. It also features a high-power and energy-efficient DC converter chip TPS54331, which supports a wide voltage input of 8-26 V and an output of 5V2A.
The board’s construction includes solid capacitors and high Q inductors components. LED indicators are present for input/output power and TX/RX communication. The board is designed to have a small voltage ripple within 100 mA. The board is ready to use upon connection, with no firmware programming required.
Please note that for the Nextion HMI display size less than 4.3”, only the USB can be used for power supply. For sizes larger than 4.3”, an external DC 8-26V power supply is recommended.
