ESP32 has integrated antenna and RF Barron, power amplifier, low noise amplifier, filter and supply Management module. The entire solution is the smallest PCB area. The board is 2.4 GHz dual-mode Wi-Fi and Bluetooth low power technology, with a wide range of safe, reliable and scalable applications for the TSMC 40nm chips, power and best RF features.
high-performance price ratio, small size, easy embedding to other products powerful, with the support of the LwIP protocol, support three modes: using AP, STA and AP and STA LUA program support, easy to develop
Simple micro switch that can be used as a limit switch, as a drawer switch or whatever you'd like. It even support higher current loads, so you can switch motors or high power leds with it (hint hint).
he level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV' pin, low voltage (3.3V for example) to ‘LV', and ground from the system to the ‘GND' pin.
