Dear Renesas Team,
Greeting from NASH,
We are implementing the Bluetooth connectivity for BMS Application, so we have following concerns kindly support us to clarify.
1. we are going to communicate DA14531MOD-00F01002 with MCU through UART protocol here challenge is our microcontroller supports for 5V signal data transmission but DA14531MOD-00F01002 is rated 3.6V, so how we can overcome this, is it ok to use voltage dividers to stepdown the signal voltage from 5v to 3,3V?
2.Can you share application schematic.
Thanks in advance, will be waiting for your response.
Hi Vasanth,Thank you for posting your question online.

You should use voltage regulators or voltage shifters to stepdown to 3.3V.

Please refer on DA14531 Module Datasheet on section 8. Application Information and on section 9. Design Guidelines.Best Regards,OV_Renesas
