Up until now you’ve had to make a choice between USB to TTL adapters and their voltage with either or selections. This USB to RS232 TTL/CMOS adapter cable eliminates that by allowing you to choose a voltage setting right at the adapter’s connection point at the terminal block.
The USB-2323TTLMOS provides a USB to RS232 port with 5V/3.3V/2.5V/1.8V TTL / CMOS compatible Logic levels. The RS232 signals include TXD, RXD, and GND. The RS232 TTL cable is USB bus powered and does not need any DC power from an external AC Power Adapter. The TTL /CMOS RS232 signals are processed on the 5-pin Terminal Block.
1.77”(L)x1.65”(W)x1.15”(H) (4.49 x 4.18 x 2.20 cm)
TTL / CMOS Serial Port
Supports one 5-pin Terminal Block TTL / CMOS RS232 Serial port snd the key benefits are:
USB Bus Powered, no External Power Supply Needed.
+2.5V or +1.8V DC Power Input Required on the 5-pin Terminal Blocks in case of Supporting 2.5V or 1.8V Logic Levels
