Actually I could find that pinout picture before, but I was not able to identify the I2C pins ( pins not mentioned ... or I am blind ). I will get the dev kits tonight... let's start with GPIO8 and 9rudi ;-) Posts: 1746 Joined: Fri Nov 13, 2015 3:25 pm Re: ESP32-S2...
Pinout The RFID-RC522 module has 8 pins, some pins are shared among three communication interfaces: SPI, I2C, UART. At a time, only one communication mode can be used. The pin are: GND pin:connect this pin toGND(0V) VCC pin:connect this pin toVCC(3.3) ...
Note: GPIO6 to GPIO 11 are not exposed to pinout of ESP32 dev kit which we are using in this tutorial. Because these pins are internally connected to the integrated SPI flash on the ESP-WROOM-32 chip. Do you want to learn the difference between a sensor and an actuator? Checkhere. ...
