5.5. Compatible Design and Applications
When testing the Wi-Fi function, a built-in Wi-Fi antenna of MC90-TE-A is recommended to be used. In this
case, resistor R213 (0
Ω, 0402 package) needs to be mounted, while resistor R211 (0Ω, 0402 package)
does not need to be mounted. If an external Wi-Fi antenna is used, then R213 needs to be mounted and
R211 does not need to be mounted.
