The ESP32-ESP-WROOM-32 development kit is an ideal kit for learning how to program the ESP-WROOM-32 module and testing its capabilities. One board contains the above-mentioned communication module / micro-controller, a USB -> UART interface based on the CP2102 chip, buttons that facilitate switching the device to programming mode and a voltage converter thanks to which the whole thing is powered directly from the micro USB connector. In addition, all pins of the ESP-WROOM module are provided as goldpin connectors, so the module can be used with any breadboard without the need for soldering. The device allows you to use Wi-Fi (802.1 b/g/n), Bluetooth / Bluetooth LE protocols and, if necessary, your own protocols written by the user.

Active cleaning foam for cleaning without streak marks on glass and smooth surfaces
A foam is produced when spraying, so it does not "run" on vertical surfaces, removing stubborn dirt
Cleans painted surfaces as well as plastic and rubber parts, without stressing the material
Saves money thanks to 20 times more efficiency

The UT-07A-EU tester indicates the correctness of the L, N, PE wiring in the electrical socket.
