Due to popular demand, we designed a version of SuperB with the ESP32-WROOM-32U module (in place of the ESP32-WROOM-32D) that allows you to connect your external antenna via U.FL connector. This option works well when you plan to enclose your SuperB in a metal box, tin foil hat or other material that interferes with antenna reception.
All Crowd Supply backers will now receive the option to receive either the built in antenna (‘Built-in trace’) or connector-compatible version to use an external antenna (‘U.FL for external antenna’). Please note that backers need to provide their own antenna solution for this option. There will be no cost difference between the two SuperB options.
If you have already placed an order for SuperB, your order will default to the built-in trace option. If you want to change this, please let Crowd Supply know by contacting them with your order ID number here: https://www.crowdsupply.com/contact/change-order
