1 | 1 | laforge | h1. multi-voltage dual USB UART |
---|---|---|---|
2 | |||
3 | This is a CP2105 based dual-port USB UART. |
||
4 | |||
5 | As a very special feature, this device allows you to manually select the UART voltage levels to 1.8, 2.3, 2.5, 2.8, 3.0 or 3.3 Volts. |
||
6 | |||
7 | It is thus ideal for a lab environment, where you frequently need to interconnect with various embedded electronics devices that have UARTs at unusual voltages. |
||
8 | |||
9 | Both UART ports feature RxD/TxD/RTS/CTS signals and have TVS diodes for ESD protection. |
||
10 | |||
11 | Miscellaneous CP2105 GPIOs are available on a separate header |
