Gateway with dwm1001 and R3B

I made gateway with R3B and dwm1001.
R3B recommends to use power more than 5V, 2.5A.
But I have only 5V, 2A and it doesn’t work.

In my case, R3B turn on led(ACT). However, dwm1001 doesn’t turn on led at all.
Is it right that It works any led on dwm1001 when I connect power on R3B?


I solve the problem.
I connected pin wrong position, center of pins instead of right upper.

Hi yeongjik.
I’m trying to make the gateway with only a DW1001 and RP3. Cannot find the minimun pins of the DW1001 to make it work, can you tell me how you make it?
