h1. multi-voltage dual USB UART This is a CP2105 based dual-port USB UART. 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. 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. Both UART ports feature RxD/TxD/RTS/CTS signals and have TVS diodes for ESD protection. Miscellaneous CP2105 GPIOs are available on a separate header h2.
