In embedded applications, serial ports are widely used communication peripherals, but embedded engineers are inevitably disturbed by various level standards and voltages of serial ports.
For historical reasons, the TTL level interface, the RS232 level interface, the RS485 level interface, the different interfaces have the characteristics, and the interface of the device preference is different.
Yu Ning technology has made embedded engineers easy to use debug module, all level conversion full coverage, is your development and commissioning of the necessary artifact!
A top 6 USB serial module! Compatible with 3.3V and 5V levels. Spend a module of money, buy 6 modules of the function!
