HL series module UART Voltage Level Translator

Hi All.

I’m looking for some advice on interfacing a microprocessor to a HL7650 module using the UART I/O. I’m using a 5V microprocessor and I believe I will need a voltage level translator to connect the HL and MPU UARTs.

Does anyone know if there is a circuit diagram showing a typical HL series UART to MPU connection via a voltage level translator ?.

At what voltage does the HL7650 UART operate ?

Can someone advise an appropriate Voltage-level Translator chip to use ?

Thanks in advance.
