High-speed Isolation USB To TTL Serial Module Power Isolation Optocoupler Isolation
Tax included.
Overview:
Optical isolation USB to TTL Serial Module Equipped with CH340T USB to serial chip, achieved the power and TTL signal isolation,
High-speed and stability, it could avoid the damage of USB and computer blue screen or other issues while use the USB to TTL
serial port module, due to improper operation or other external impact on the computer , could improve the safety of debugging.
The function and characteristics:
1. Onboard 500mA self-recovery fuse and 5V isolated power supply module to protect the computer from damage
2. Onboard stable CH340T USB to serial chip
3. Serial TTL level through the optocoupler isolation, fast (up to 921600bps), high reliability
4. Output TX RX end with protection diode function, can improve the impact resistance
5. Computer USB end and serial port output end realize complete electrical isolation
6. Output TTL level can be set to 3.3V / 5V
7. Serial output maximum output current of 150mA
8. The board size: 55x26mm
Feature:
- 3.3V, 5V: Output supply voltage and TTL level switching pin
- VCC, GND: Power supply output pin
- The TX, RX, GND and VCC pins of the serial port module are connected to the RX, TX, GND, and VCC pins of the user equipment.
When the isolated serial port module VCC pin with a jumper cap 5V, the output 5V TTL level and power supply voltage;
while VCC pin with 3.3V jumper cap, the output level of 3.3V TTL and power supply voltage. The following is an example of using
the isolated serial interface module to debug the 3.3V ESP8266 module (With the jumper cap to isolate the serial port module
VCC and 3.3V shorted, isolated serial port module TX, RX, GND, VCC respectively ESP8266 RX, TX, GND, VCC), as the picture shows:
