|
||||||
|
* - GPIO Header 2
|
||||||
|
- Five unpopulated through-hole solder pads to provide access to selected GPIOs of ESP32. For details, see `GPIO Header 2`_.
|
||||||
|
* - Function Switch
|
||||||
|
- A 4-bit DIP switch used to configure the functionality of selected GPIOs of ESP32. Please note that placement of GPIO pin number marking on the board's silkscreen besides the DIP switch is incorrect. For details and correct pin allocation see `Function Switch`_.
|
||||||
|
* - Tx/Rx LEDs
|
||||||
|
- Two LEDs to show the status of UART transmission.
|
||||||
|
* - FT2232H
|
||||||
|
- The FT2232H chip serves as a multi-protocol USB-to-serial bridge which can be programmed and controlled via USB to provide communication with ESP32. FT2232H also features USB-to-JTAG interface which is available on channel A of the chip, while USB-to-serial is on channel B. The FT2232H chip enhances user-friendliness in terms of application development and debugging. See `ESP32-Ethernet-Kit V1.1 Ethernet board (A) schematic`_.

|
||||||
|
- Power On/Off Switch. Toggling the switch to **5V0** position powers the board on, toggling to **GND** position powers the board off.
|
||||||
|
* - 5V Input
|
||||||
|
- The 5 V power supply interface can be more convenient when the board is operating autonomously (not connected to a computer).
|
||||||
|
* - 5V Power On LED
|
||||||
|
- This red LED turns on when power is supplied to the board, either from USB or 5 V Input.
|
||||||
|
* - DC/DC Converter
|
||||||
|
- Provided DC 5 V to 3.3 V conversion, output current up to 2 A.
|
||||||
|
* - Board B Connectors
|
||||||
|
- A pair male and female header pins for mounting the `PoE board (B)`_.
|
||||||
|
* - IP101GRI (PHY)
|
||||||
|
- The physical layer (PHY) connection to the Ethernet cable is implemented using the `IP101GRI <http://www.bdtic.com/DataSheet/ICplus/IP101G_DS_R01_20121224.pdf>`_ chip. The connection between PHY and ESP32 is done through the reduced media-independent interface (RMII), a variant of the media-independent interface `(MII) <https://en.wikipedia.org/wiki/Media-independent_interface>`_ standard. The PHY supports the IEEE 802.3 / 802.3u standard of 10/100 Mbps.
|
||||||
|
* - RJ45 Port
|
||||||
|
- Ethernet network data transmission port.
|
||||||
|
* - Magnetics Module
|
||||||
|
- The Magnetics are part of the Ethernet specification to protect against faults and transients, including rejection of common mode signals between the transceiver IC and the cable. The magnetics also provide galvanic isolation between the transceiver and the Ethernet device.
|
||||||
|
* - Link/Activity LEDs
|
||||||
|
- Two LEDs (green and red) that respectively indicate the "Link" and "Activity" statuses of the PHY.
|
||||||
|
* - BOOT Button
|
||||||
|
- Download button. Holding down **BOOT** and then pressing **EN** initiates Firmware Download mode for downloading firmware through the serial port.
|
