r/ESP32Marauder

Since launching the NM-CYD-C5 (the ESP32-C5 based CYD variant with dual-band WiFi 6), the single most common piece of feedback has been:

"Could you make a 1u variant that I could connect an antenna to?"

"Does it have external antenna connector"

"Will an external antenna be supported this time, or is a DIY solution again required to attach an external antenna?"

Fair point. 5GHz attenuates much faster than 2.4GHz, and a small PCB trace antenna surrounded by a display and ground planes has its limits.

So: the NM-CYD-C5-Colorful-Ant is coming.

• IPEX-1 connector + bundled dual-band 2.4G/5G antenna • External antenna only — no onboard PCB antenna on this version • Same ESP32-C5 (dual-band WiFi 6, BLE 5.3, Zigbee/Thread), same 16MB Flash + 8MB PSRAM, same CYD-compatible footprint • Still works with Bruce / Marauder / ESPHome, etc as before

The default External Antenna Parameters

• Frequency range: 2400-2500MHz / 5000-5800MHz
• VSWR: 2400-2500 ≤ 2.5, 5000-5800 ≤ 2.5
• Efficiency %: 2400-2500: 83.3 AVG; 5000-5800: 73.8 AVG
• Peak Gain (dBi): 2400-2500: 3.2 AVG; 5000-5800: 3.7 AVG
• Radiation Properties: Omni-directional
• Polarization: Linear

The 3D printed shells (see from the picture) will be released on GitHub repository soon.

Guys I have built a DIY 1.8 inch TFT Display ST7735 Module With Only 50Rs/0.5$ The PCB Is Totally Hand Made Using Toner Transfer Paper And Working Quite Well The All Source Header Files For different ESP Boards are in the github repository with schematics diagrams, Pinout Of the module, Proper documentation has been in the video and github repository please follow it, it use TFT_eSPI Library

Did some firmware updates to the Marauder 1.14.1 to see what else this device could do. Added some BTE sniffing and spoofing capability from nyanBox and BLESploit repos, plus drone detecting and spoofing on WiFi, Jammer detector that baselines the current environment and then shows discrepancies, and camera detector/deauth.

Added persistent user-generated SSIDs that will remain through reboot so they don’t have to be re-entered through the text input. And most importantly, added several games in a new games menu. Might add a slot-machine, roulette, and Pac-Man type game as well for fun.

Upgraded recently to the Bolton Dart WiFi Omni Monopole Antenna, 2.4/5.8–7.125 GHz; and I think it’s safe to say that these antennas have been my favorite by far. Curious about what you guys think of the look with the white on black.

Yo guys, finally I made my marauder work, but there are some issues

1. No response of ble attack

2. Inaccurate response of wifi attacks

3. Screen isn't calibrated, tried many possible things, no luck.

Screen is ST7789 2.8inch TFT, and ESP32 only, wroom version not official one but btw.....

I have several questions I need help with if someone can please help! 😭 (At the end with ❓)

I am trying to build a device that is very capable and max out what it can do. There’s nothing specific I am setting up for I just want to to be able to jam , to spam and have sub ghz and WiFi 2.4/5/6 capability and learn to protect myself.

! I have a nm-cyd c5 running launcher and have a secondary esp32 c5 wifi6 dev kit. I plan to add a lot more components to the build such as

4 ebyte e01-ml01dp5
1 flux capacitor by rabbit labs (c1101 +amplifier )
1 sequre m10-18 gps converted to ipex antenna
1 900m30s LORA with ipex antenna and 915mhz meshtastic antenna
1 nm cyd-c5
1 esp32 c5 wifi6 dev kit

If needed I do have :
Cyd esp32 s3 converted to external antenna
esp32 s3 lonely binary dev
Esp32D

I don’t have any specific plans for the build except learning and I am more interested in learning more nefarious things to better understand them and be able to recognize when I am vulnerable. So whatever firmware gives me the most freedoms I saw a repo for m5 but the firmwares stated they had very specific Purposes. Thank you!

❓if anyone knows what traces to cut for external antenna plug on c5

❓if I’m using c5 cyd with launcher What firmware for esp32 slave? Should I use the c5, s3 , wroom etc

❓what antennas or components should not be placed near the other?

❓Is there a better pairing of esp32 for my build ?

❓any other ways I can improve my device? Any advice.

❓ the ebyte e01- can I combine them say 2 to save space and would i be able to double the reach?
Also how do I tell which ones are fake? I have a pair that look very different than the other pair.

❓is it true I shouldn’t add a screw on amplifier to the flux capacitor because I have the Lora?

❓is the gps only good for war driving? (I have no interest in it)

❓ is there any reason to also use the nrf24 I have? I have like 5-6 laying around.

Thanks in advance!

After several tests and a few setbacks (I don’t recommend starting by soldering directly onto the board—do your initial testing on a protoboard first), my favorite apps are BT-Jammer and Evil Portal.😈
Any firmware you’d recommend trying out? Greetings from Mexico!! 🇲🇽

Added new looks/theme and some bug fixes.
Available via Launcher OTA...
