  • Page 33 Rev. 1: 13-04-2021 I/O ESP32 PLC 3.3V pins The ESP32 ETHERNET&WIFI&BLUETOOTH PLC has some of the ESP32 board pins available. These pins can be programmed according to Raspberry features such as I/O’s operating at 3.3V or any additional features present in the pins (for example I2C communication in pins SCL and SDA).
  • Page 34 ESP32 ETHERNET&WIFI&BLUETOOTH PLC RTC Module is based on the DS1307 Chip. This chip works with the I2C protocol communication, so it is required to have enabled the I2C protocol. Using the boards of Industrial Shields, there is a library that simplifies the RTC implementation called RTC.
  • Page 35 The microSD uses the SPI communication to interact with the ESP32. The SPI protocol is always enabled, as there are no switches that configure it. Using Industrial Shields’ boards there is a library that simplifies the uSD implementation called The microSD uage is conditioned by the switch configuration. See the Section Verify that the CPU is not actively running a process before inserting the memory card.
