Product Description of USB 2.0 to TTL Module
CP2102 chip is a single-chip USB to UART Bridge IC. This module required minimal external components.
Features of USB 2.0 to TTL Module:
It is an able and reliable chipset CP2102.
Its USB specification is 2.0 compliant and its speed is 12 Mbps.
Its standard USB type is a male and TTL 6 pin connector.
6 pins are consisting of 3.3V, RST, TXD, RXD, GND, and 5V.
Its baud rate is 300 bps to 1.5 Mbps.
It is 640 bytes transmit buffer.
It has hardware or X-on/X-off handshaking support.
It has an event character support line break transmission.
It is USB suspend states supported via suspend pins.
Its temperature range is -40 to +85.
Its size is 42mm x 15mm.
Its weight is 4g.
Pin Configuration of USB 2.0 to TTL Module:
TX is a Transmit pin of the microcontroller. RX pin performs the transmission process of CP2102.
RX pin works as a receive pin of the microcontroller. TX pin of the microcontroller is just a data receiving the pin.
The RST pin is normally unconnected. It is reset pin for CP2102. This pin initiates a system to reset by driving this pin low for at least 15 us.
GND pin is ground. It should be common to microcontroller ground.
3.3V is optional output to power and it is an external circuit up to 50mA.
5V is optional to power. And its external circuit up to 100mA.
