From AWR2243BOOST's document, I knew board Rev A's capacitor C56 was changed from 220nF to 47nF in board Rev B.

1. Would this change bring completely different performance?

2. There is no clear evidence that shows my board's version. How can I know it's A or B?

Hello,

The revision should be highlighted on the silicon screen near the 60 pin connector of the Boost EVM. The capacitor that is changed is the Bandgap decoupling capacitor (VBGAP).

I can only see 'PROC099A-001'. No other information can be found.

By the way, my 5-V LED won't glow. I guess there's something wrong in the hardware.

Hello,

What is the power Supply rating you're using?

Also, can you send a picture of your setup?

I don't know what 'power supply rating' means.

Hello,

Thankyou for the picture of the setup. PROC99A is revB.

Also, for the connections, have you followed the AWR2243 Boost user guide and DCA1000 quick start guide for start up?

I don't see the device boot up after supplying power. Is it a 5V supply you're using? What is the current rating?

Regards,

Ishita
