Sell [Pc] Usb To UART TTL USB To Serial Port Converter Module jIw6 best price

Usb to I2C IIC USB to UART TTL USB to serial port auto converter module YS-CH341T Features: the board adopts 6Pin interface, spacing 2.54 mm. Made of high-quality and selected materials.Long service life. The external voltage is in line with the switching chip. Can also serve as an output end to supply external power. Usb power supply, 3.3V, TTL 3.3V, suitable for 3.3V TTL system, can provide 3.3V voltage to the outside, initial out-of-plant configuration; 5V TTL 5V level, suitable for 5V TTL system, can provide 5V voltage to the outside. Specification: model: YS CH341T module/USB to 12C module Size: approx. 5.5x1.5 cm/2.17x0.59in Material: metal+plastics Rxi, TXO, GND, VCC, SDA, SCL (panel corresponding position marked) The definition is as follows: Rxi: input, TTL serial reception signal (metmcuoftx); Txo: output, TTL serial port transmission signal (for MCUOfRX); Gnd: signal location; Vcc: system power supply, Sda: i2cbus Serial Data (integrated pull resistance without external pull); Scl: i2cbus vital lock (integrated pull resistance without external pull). Usb 2ic function: satisfy SCL SDA GND, VCC no answer; Usb 2 ttl function: connect RXI TXO GND, VCC no answer; Packaging includes: 1 X YS CH341T module Note: due to the lighting effect and shooting angle problem, the product will have some tolerance, please forgive me. Allow error of 0-1 cm due to manual measurement.
