I would like to try out some stuff with the ESP8266 12-E. But my first problem ist to find out the minimum wiring. So I wrote a little schematic myself. It would be nice if somebody could tell me if everything is fine or could me give some hints how to improve the schematic Of course, in the final version I will add some 100nF capacitor for better power supply.
With this schematic, I can freely use the GPIOs 4, 5, 12, 13, 14 and 16, the ADC, the SPI-Interface (MISO, MOSI, SCLK) and CS0, right? For example, to add some DHT22, DS18B20 and stuff like this.
