The wESP32 is an ESP32-based core board with wired Ethernet connectivity and power over Ethernet (PoE). It was designed to help you quickly create zero-setup, single-wire-installation network-connected devices. By combining a powerful microcontroller with excellent community support, 13 W of available power, reliable connectivity, and a compact footprint, the wESP32 gives you a head start in your next IoT design and lets you focus on your application.

Features and Specifications :

Programming :

Optional wESP32-Prog module for programming
USB serial console via same wESP32-Prog module

Expansion :

20-pin header footprint with 3.3 V, V+ power, and 15 of the ESP32 GPIOs available for your application
wESP32-Prog module can be plugged in as needed or permanently soldered

Physical Characteristics :

Full data and power path isolation in compliance with the IEEE 802.3at 1500 Vrms isolation requirement
Compact 75 mm by 40 mm footprint with 4 mounting holes compatible with common M2.5 or 4-40 screws
High-quality PCB with two oz copper and mounting hole designed to sink heat away from the PoE PD controller for optimal thermal performance

wESP32-Prog :

To be able to program the ESP32 on the wESP32, we created the wESP32-Prog submodule. It is a tiny module with micro USB, based on the well-supported Silicon Labs CP2102N, and includes the ESP32 auto-programming circuitry so that the circuitry doesn’t need to be duplicated on every target board and no buttons need to be pushed for programming.

The wESP32-Prog can be used both as an ESP32 programmer and as a USB serial terminal during development or in production as needed. Since the wESP32 provides full data path and power path isolation, the user can safely have the USB connected to their PC while the Ethernet cable is plugged in to the wESP32.

The wESThe wESP32-Prog was not just created as a bench tool but can be permanently installed in deployed wESP32 units by inserting it into the programming port and soldering the connections, thus becoming a permanent part of the wESP32. It may be necessary to clip the pins off after soldering if they are too long.

The wESP32-Prog was not just created as a bench tool but can be permanently installed in deployed wESP32 units by inserting it into the programming port and soldering the connections, thus becoming a permanent part of the wESP32. It may be necessary to clip the pins off after soldering if they are too long.

If the user does not need this port in deployed units, the staggered programming port footprint on the wESP32 allows the wESP32-Prog to be temporarily friction-fitted just for programming. Note that continued pressure may be necessary to ensure good contact during programming, for this reason it is recommended to permanently solder the wESP32-Prog to a wESP32 that is used for development.

There is nothing special or proprietary about the wESP32-Prog, other than that it was created specifically to be suitable for production use. So if you already own another ESP32 programmer, you can use it with the wESP32 as well. Note, however, that since there are so many variables and places where things could go wrong when using your own programmer, we only offer customer support if you are using a wESP32-Prog. If you use your own programmer, you’re assumed to know what you’re doing and you’re on your own!
