Hi for all,
i built the project but unfortunately it does not work.
Trying to reverse the TX and RX pins it work but when i launch the [ESP32] Marauder application the device restart by itself due to crash.
I attach the photos of the module ESP32:
and the error flipper zero:
Can you help me? The idea is good.
Thanks for all answers.
That flipper APP (ESP WiFi Marauder is to be used with the Flipper WiFi dev board flashed with Marauder firmware… Meaning it was not written for this specific mod/tool/project. Also check if the version of your firmware (on flipper) is compatible with the version of the app that you are using (compiled for the correct API).
Hi Spildit,
in flipper zero I installed the release Eng1n33r:
flipper-z-f7-update-un4-0f9ea9
ESP32 Marauder is pre-installed.
In ESP32 chip I installed the firmware justcallmekoko:
esp32_marauder_v0_9_15_20220907_flipper
Did you see any error? I dont think that this issue depends by software but eletronics.
It is possibile invert the TX and RX pin by flipper zero software? Because the PCB has issue in pinout TX and RX, it is inverted .
Thanks for the support.
The error most likely is related to the fact that the app on the Eng firmware you mentioned is made to work with the official wifi dev board with Marauder on it and NOT on the ESP mod that you did mention…
Try to buy flipper official debug wifi dev board and install the Marauder firmware on it, check if the app on the flipper do work with that.
Ok, thanks, the problem is that WiFi Devboard is soldout, but i will wait that it is available.
Thanks for the support.
No problem. Let me know if you manage to make it work later with the dev board. Regards.
Oh yeah it looks like the pins have been switched. I’ve designed a revised version of the board here: OSH Park ~
Changes:
It hasn’t come in yet, so I don’t know if it’ll work
As for why the ESP Marauder doesn’t seem to be compatible, this module uses an ESP32-S instead of an ESP32-S2 (which is what the Wifi Dev Board) uses. I suspect that it should be possible to recompile ESP Marauder to work on the ESP32-S.
Thanks for sharing the second version of the project.
Is it possible to draw the PCB for ESP32-S2 WROVER?
This should be exactly the chip installed on the original development board.
By doing this we should minimize the incompatibility problems.
Thanks antimatter15 !
Hi, I tested the ESP32-S with the Marauder Firmware and work fine, i bought the pcb fixed. Thanks for all .
New version of the circuit board seems to work (using Marauder Mini firmware rather than the Flipper version)! My PR for adding pins 16/15 as DTR/RTS pins was landed recently which should make flashing/reprogramming much easier.
I love the design and I’d like to create one myself.
besides the board and ESP-S2-module, what other parts do I need for this?
Hey mate, looks awesome, is there any BOM list? I see in the bottom side some footprints c1 c3 R1 LED1, looks like a led, resistor, and… but le me knwo what we need 
Thanks and congrats by the initiative.
Probably
awesome thanks!

Can you send me the products link of the working version, i would like to buy the components thx.
Hello my friend, could you send me the links of what you used tu build the working esp 32, thx
Any update on this? Would love a parts list as well.
