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 |
