Hi,

1. You can leave DC_BOOST and EN pins floating.

2 C676, 677, 678, 679 need to be 330nF instead the 220nF.

Thanks

Hi David

Thanks for your reply

1.You can leave DC_BOOST and EN pins floating.

DC_BOOST >> Reserve 0ohm to GND

EN >>Why needs to floating?

2.C676, 677, 678, 679 need to be 330nF instead the 220nF.

Hi,

The EN pin already has an internal ~400k pullup, so you can leave EN pin to be left unconnected or tied to a 100nF capacitor to GND.

Thanks

Hi David

Follow up your recommendation for EN pin floating.

Additional, I added those 200K to GND for RX signal, the default is stuff.

Please help to check.

Hi,

The latest schematic looks ok.

Thanks

David
