#140 I²C testpoint traces interfere with antennas

I²C testpoint traces cause interference

Problem environment

To foster research and exploration, test points TP5 and TP6 break out the clock and data of the controller's interintegrated circuit (I²C) with copper traces that cross antennas’ keep out areas.

Steps to reproduce

  1. Refer to the layout are of AE1 and AE5
  2. Locate traces between test points and SCL/SDA

Expected result

Copper traces do not cross antenna keep out areas.

Actual result

TP5 and TP6 connect to traces that cross AE1 and AE5.

Workaround

It is acceptable to temporarily keep the interference until higher efficiency in the on board antennas is needed more.

Severity level

This is low priority because project requirements do not mandate antenna choice.
