hello,

can someone help me please,

Can TDC1000-7200EVM work without USB, by using battery 2AA or 2AAA?

Hello Sara,

The TDC1000 itself can be powered with as little as 2.7V, however the EVM needs a 3.3V supply for the clock buffers. I would suggest using 3 AA or AAA batteries instead.

It would be easiest to just cut a USB cable and apply power to the VBUS pin and GND, then plug this into the EVM. There is no test point for the board power, but the USB connector side of C19 or C22 would be another place to connect the power.
