We have developed an Industrial Grade Isolated USB to UART converter.
In embedded systems, UART/serial ports are mainly used to view debug messages, to flash the program or to configure the device via command/response protocol.
The Industrial Grade Isolated USB to UART could be useful in various use cases.
High Voltage AC / DC Circuits
Isolated USB to UART Converter is mainly helpful for companies/engineers involved in building power electronics products or dealing with high-voltage DC or AC signals on their boards and want to connect them to a Laptop or PC safely.
Connecting the board with HV AC or DC to a Laptop or PC USB port without isolation may damage the port or laptop. Non-isolated USB to UART converters also induce leakage currents in many situations and can significantly increase noise.
Low Power Embedded Designs which needs 2.5V/1.8V
If you are working on Low-Power Designs like battery-powered asset trackers, wearables, or any battery-powered device, where UART is at a lower voltage level, you will need a USB-to-UART converter that supports those voltage levels.
That’s why CAPUF Embedded’s Isolated USB to UART Converter will help as a voltage section(1.8/2.5/3.3/5.0V) is provided.
Medical Electronics / Noise Sensitive circuits
As safety/induced noise is a great concern in many designs, an isolated USB to UART converter provides the best solution to connect your Embedded Board or product safely with a Laptop or PC.
What is Unique about our Isolated USB to UART Converter?
- The board is designed and manufactured in India.
- A 4-channel DIP Switch is provided for an easy voltage level selection (1.8V/2.5V/3.3V/5.0V).
- Not just RX and TX but RTS, CTS, DSR, and DTR are also provided.
- The board can supply ~100mA of power. This power-sourcing capability helps make the setup easy when testing a board that doesn’t need much power.
- It provides Galvanic Isolation. Both Power and IOs are Isolated.
Salient Features
- USB-C Port: To connect to a PC, one can use a USB-A to USB-C cable or even a USB-C to USB-C cable.
- USB to UART Bridge capable of up to 3Mbps
- Isolated Power, capable of up to 100mA. Short Circuit Protected.
- Isolated RX, TX, RTS, CTS, DTR, DSR, and all IOs are ESD-protected.
- Signal voltage level selection 1.8/2.5/3.3/5V via DIP Switch
- A 2-pin Jumper is provided to select if you want to power the target(Jumper ON) or if it will be self-powered.
- LED Indication for RX, TX, & Power
- A male 8-pin header (angled) comes in the package but is unsoldered.
- Compact Size: 30.5mm x 70.5mm
