SuperB marries two of hardware’s ubiquitous names - the "Bee" form factor and ESP32. The Bee form factor was derived from DIGI’s XBee industrial grade IoT boards. This form factor has long been used to add wireless connectivity to hardware across the board. But in the maturing market of connected items, two protocols stand as required: Wi-Fi and Bluetooth. ESP32 brings both, and in an easy-to-use package - giving maximum flexibility to your existing hardware and for your next generation of modular, extensible products.

We designed SuperB with options to accommodate two styles of antennas. There will be no cost difference between the two antenna options.

Built-in ‘trace’ antenna: This is the original SuperB design. It uses the ESP32-WROOM-32D module, and the antenna is built into the device.

U.FL for external antenna: This option uses the ESP32-WROOM-32U module, and 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. Please note that backers need to provide their own antenna solution for this option.
