<br>We need to remove the smd inductor (2) shown in the Figure below because it has a ferite core, which would be saturated in MR envrionment and may damage the hardware. This inductor is needed for the DC-DC regulator of the SoC. You can continue without replacing another inductor and use the global LDO regulator. The global LDO consumes [30% more power][1b] than the default DC-DC buck converter. Instead of replacing the inductor with a air-core equvalent value, global LDO is better for the size constraints and simplicity. Please make sure that the internal DC/DC regulator is properly configured, if global LDO is used. The instructions are shown in the **firmware** section

<br>We can configure the _2.4 GHz_ antenna for MRI setting. First, we need to remove the SMA connector from the [breakout board][1] as indicated with (3) in the Figure below. Then, the port of the antenna output from the board should be connected to the protection filter via an coaxial wire. The other port of the protection filter can be connected to the [external antenna][8]. Currently, there is no dedicated port in the implementation. Therefore, the connector needs to be stripped and soldered to the filter.

<br>Finally, we can solder the [headers][ay] to connect the breakout board to the main PCB. There is no need to solder header to the each pin. Nevertheless, the modified breakout board should look like similar to the one at the top of the Figure.
