12.3.1 Recommended External Antenna for ATWINC15x0-MR210UB
Whip Antenna (Part number: RN-SMA-4) along with a 10cm length RF cable assembly (u.FL to SMA) has
been used for the certification of ATWINC15x0-MR210UB. It is recommended to use the same or similar
external antenna in design.
12.4 Module Assembly Considerations
The ATWINC15x0-MR210xB modules are assembled with an EMI Shield to ensure compliance with EMI
emission and immunity rules. The EMI shield is made of a tin-plated steel (SPTE) and is not hermetically
sealed. Solutions like IPA and similar solvents can be used to clean the ATWINC15x0-MR210xB module.
However, cleaning solutions that contain acid should never be used on the module.
The ATWINC15x0-MR210xB modules are not intended for use with a conformal coating and the customer
assumes all risks if a conformal coating is applied to the modules.
