Microchip RN-SRL USB to 3V & 5V Serial UART Dongles & TTL Bridge Cables

Microchip RN-SRL USB to 3V & 5V Serial UART Dongles are USB-to-Serial TTL bridge board modules (PCB Assembly) designed to accommodate a quick and easy means to interconnect to devices having TTL level serial interfaces which require conversion to USB. The on-board bridge controller is either the PROLIFIC 64-bit PL2303HXD (3V) or FTDI's FT232R (5V) USB-to-Serial UART device which controls the relevant USB signal and protocol requirements.

The Microchip RN-SRL USB to 3V & 5V Serial UART Dongles are each comprised of 2 main components, a USB type-A connector as the interface to the outside world, and small form factor PCB requiring soldered-wire connections to the mating device(s). The RoHS compliant PCB assembly is configured with a fixed TTL output level of +3.3V or +5V. Microchip RN-SRL USB-to-Serial TTL Bridge Cables are available in black and translucent overmold USB-A male connectors, having connection-ready 6 conductor tinned-leads at the opposite end. Each cable is made up to a 6 foot length (1.8m), with a heat-shrink finish treatment.
