The difference between USB2Serial Light and UC-2102 and UC-340G

 

No.	Item	BUONO USB2Serial Light	UC-2102	UC-340G
1	USB Chip	C8051F321	CP2102	CH340G
2	UART Voltage Level	TTL-3.3V	TTL-3.3V	TTL-5V
3	Pinout	Same	Same	Same
4	5 times DTR toggled after power up (The will lead the Arduino MCU reset 5times , delay the power up speed)	NO (Good)	Yes	Yes
5	Driver	Arduino Native driver	Form Silabs	Form WCH
6	Cost	High	Mid	Low
7	Known issue	No	No	Can not used with Arduino IDE 1.6.8 , it will cause the MCU reset repeatedly
