Tip from a customer - If the ESP module's PCB antenna is painted black, the IPEX antenna connector is used by default. This can be changed to the PCB antenna by resistor modifications. - 13.6.2022

There have been two versions of the product, but the current stock and future products have the IPEX antenna connector. - 13.6.2022

The sleep current of the ESP32 chip is less than 5µA making it suitable for battery powered and wearable electronics applications. ESP-WROOM-32 supports data rates of up to 150Mbps and 22dBm output power at the PA to ensure the widest physical range.
