Mini ESP32 Wifi Module

3rd-party modules

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:

  • Fixed the issue where TX/RX have been flipped
  • Added an LED connected to GPIO4 for ESP32
  • Added an on-off switch to enable/disable the wifi module (to save power)
  • Replaced programming header with a PCB jumper, so that in theory the ESP32 could be flashed using the Flipper USB-UART bridge by pressing something conductive against it while turning on the module
  • Added space for another bypass capacitor for better power stability

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.

Here’s a variant that uses the ESP32-S2 WROVER OSH Park ~

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?

#23

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 :slight_smile:

Thanks and congrats by the initiative.

  • D1: 2V LED
  • R1: 68 R
  • C1: 0.1 uF
  • C2: 10 uF

Probably :slight_smile:

Any chance you had a part number for the switch on the S2 version? I believe I have found everything else I need on Mouser, but I don’t think I can find a switch small enough.

Thankyou for your time.

Hey can we all have a parts list please. TY!

#32

This is the switch you need. You’re welcome.
