22.8.2018 Pmod ESP32 Reference Manual [Reference.Digilentinc]

https://reference.digilentinc.com/reference/pmod/pmodesp32/reference-manual 1/8

The Digilent Pmod ESP32 features a radio with support for 802.11 b/g/n Wifi and dual-mode Bluetooth. This module is perfect for

connecting your FPGA or microcontroller projects to your home network, the internet, or any bluetooth hardware. The Pmod ESP32

contains a Tensilica Xtensa microprocessor, which can be operated in slave mode with AT commands over a UART interface.

Additionally, the Pmod ESP32 can be operated in standalone mode and run custom applications. In slave mode, the module can be

configured as an access point to host a Wifi network, or a station to connect to an existing network. Slave mode functionality over UART

is made easy through the use of a well documented AT command set

(http://espressif.com/sites/default/files/documentation/esp32_at_instruction_set_and_examples_en.pdf). An additional UART port is provided

on the top of the module for system debugging and firmware flashing. Standalone mode gives the user access to the full API and SDK

provided by Espressif (http://esp-idf.readthedocs.io/en/latest/get-started/index.html) for operation through the use of the Xtensa tool-chain.

The Pmod ESP32 is a great and cost-effective way to add WiFi and Bluetooth to any project.

22.8.2018 Pmod ESP32 Reference Manual [Reference.Digilentinc] The Pmod ESP32 has the ability to operate in slave mode using the UART interface on the top row of pins. In slave mode, the device responds to a specific set of AT commands. More information about the AT command firmware can be found here:  ESP 32 AT Source (https://github.com/espressif/esp32-at). The device comes pre-configured with the AT command firmware installed.
