This is a family of ESP32-based modules with some integrated key components, including a crystal oscillator and an antenna matching circuit. The modules constitute ready-made solutions for integration into final products. If combined with a few extra components, such as a programming interface, bootstrapping resistors, and pin headers, these modules can also be used for evaluation of ESP32's functionality.
