Wifi And Bluetooth Module - Cherry theobroma SYSTEMS PX30-mQ7 User Manual

10.5 Wifi and Bluetooth module
The WiFi and Bluetooth are part of the ESP32 PICO MINI 02U module on the PX30-uQ7 board. The antenna connector
on the module is w.FL type. The firmware running on the ESP32 is flashed in its internal memory and unlike most wireless
modules, does not require files to be present in the root filesystem. This also means that a firmware upgrade is slightly more
complex since it needs to be flashed.
The following pins are used for boot and reset.
