Hi all,

I have some confusions about the PCB routings of nRF2401.
In the nRF2401 product spec, pins#24, 20 and 17 are connected togther to Vdd. From the Nordic given PCB layout, the routings of these 3 pins seem touching (or passing through) the center pad of the die, which is supposed to be ground, right?

What things should I do in the layout so as to prevent any shorting?

Thx!

Pin 20 is Vss (Ground)! I'd use the application example in Fig. 20 as a guide.

hello fyaa
i am sorry for my bad english .

#24,#21 and #17 are vdd and must conected to 3.3v and #22,#20,#18 and #16 must conected to GND .
(nrf2401 and not nrf24e1 or other .)

yeah if you read closer you will find that they use a silkscreen.
the center pad should be connected to gnd
