ESP8266 Wifi Module

Product Details:

ESP32 has five strapping pins:

• MTDI
• GPIO0
• GPIO2
• MTDO
• GPIO5  

Software can read the values of these five bits from register ”GPIO_STRAPPING”. During the chip’s system reset (power-on-reset, RTC watchdog reset and brownout reset), the latches of the strapping pins sample the voltage level as strapping bits of ”0” or ”1”, and hold these bits until the chip is powered down or shut down. The strapping bits configure the device’s boot mode, the operating voltage of VDD_SDIO and other initial system settings. Each strapping pin is connected to its internal pull-up/pull-down during the chip reset. Consequently, if a strapping pin is unconnected or the connected external circuit is high-impedance, the internal weak pull-up/pull-down will determine the default input level of the strapping pins. To change the strapping bit values, users can apply the external pull-down/pull-up resistances, or use the host MCU’s GPIOs to control the voltage level of these pins when powering on ESP32. After reset, the strapping pins work as normal-function pins.
