ESP32-PRO development started long time ago but with so many projects running in parallel it was always on the bottom of the priority list which was not quite fair for this board as it has excellent features:

32Mbit (4MB) PSRAM which maps on ESP32 memory space and can be used for your project.

32Mbit (4MB) fast QSPI Flash for program memory mapped to ESP32 program space.

Additional PIC32MX270F256DT processor with USB-OTG 256KB Flash and 64KB RAM which can be used as program or as USB profile like USB keyboard, serial, MIDI etc you name it.

ESP32-PROa

LiPo battery charger and management IC.

Optional Crypto engine for IoT applications.

We made two demo projects with this board which create WiFi to serial bridge you can pair two such boards and use them as wireless UART or Wireless USB Serial bridge, but the possibilities are many as the USB-OTG allow you to connect Web cameras, Flash drives and many other USB devices.

    Will this come with ce conformity? I know dev boards are exempt, but radio modules are a bit problematic without even when exempt…

    Can the PIC32MX270F256DT device be mountted as a Mass Storage device and program the ESP32 module by dragging a file on it?

      This is great idea. I have recently seen a lot of boards with this kind of programmers – very easy to use for complete beginners and work on practically all platforms (All normal OSs have built in drivers for USB mass storage devices).

        That is the idea. An easy way for beginners (and no so expert companies) to use your boards. Hope this can happen!!
