Update Marauder on the PINGEQUA Scout Lite

The PINGEQUA Scout Lite is a compact dual-band ESP32-C5 wardriving board for the Flipper Zero — GPS (Quectel L86) and microSD logging on top of 2.4 GHz and 5 GHz Wi-Fi recon. It ships pre-flashed with ESP32 Marauder and works out of the box — just mount it on the Flipper GPIO header. Use this page to update to a newer Marauder build or recover the firmware, directly from your browser — nothing to download or install. You need Chrome, Edge or Firefox 151+ on a desktop computer and a USB-C data cable.

Hold BOOT to connect

The Scout Lite connects over the ESP32-C5's native USB, so you hold the BOOT button to enter download mode: hold BOOT, plug in the USB-C cable while holding it, release BOOT, then click Connect. A failed flash is always recoverable by reflashing.

This page only flashes ESP32 Marauder

Scout Lite ships pre-flashed with ESP32 Marauder. Use this page only to update or recover Marauder. Do not flash SigRoam onto the ESP32. SigRoam is a Flipper Zero .fap, not board firmware. A dedicated scanner firmware is in development; it is not in the flasher. Shipping units stay on Marauder.

Do I even need to flash it?

No — the Scout Lite comes with Marauder pre-installed. Reach for this page only to update to a newer Marauder version or to recover a board whose firmware got interrupted.

How do I update it?

1. Hold BOOT on the Scout Lite.
2. While holding BOOT, plug in the USB-C cable (or tap RESET if it's already connected).
3. Release BOOT.
4. Click Connect, choose the serial port, then Flash.

Why do I have to hold BOOT?

The ESP32-C5's native USB doesn't yet support automatic download-mode entry in the browser flasher, so it needs the manual BOOT press. A board that adds a USB-UART bridge (CP2102 / CH340) with an auto-reset circuit would flash without touching any button.

Which browsers can flash the Scout Lite?

Browser	Supported
Chrome / Edge (desktop)	✅ Yes
Chrome (Android)	✅ Yes
Firefox 151+ (desktop)	✅ Yes — first use adds a permission add-on
Safari (macOS / iOS)	❌ No
Firefox (Android)	❌ No

Browser flashing relies on the Web Serial API: Chrome and Edge on desktop, Chrome on Android, and — since Firefox 151 for desktop (May 2026) — Firefox. Safari and every browser on iOS are out; see Web Serial is not supported.

Troubleshooting

Symptom	Fix
No port in the picker	Follow No serial port detected, then re-enter the C5 ROM port with the download-mode guide.
"Failed to connect" / can't read chip	Use the hardware-tested Scout Lite download-mode sequence, then retry.
Black screen / no response after flash	Re-flash and let it complete; the C5 ROM download mode is always recoverable.

What is the Scout Lite?

The Scout Lite is PINGEQUA's ESP32-C5 wardriving expansion board for the Flipper Zero. It logs Wi-Fi networks with signal strength, channel and GPS coordinates in WigleWifi CSV format to the Scout Lite onboard microSD (not the Flipper card), ready to upload to the WiGLE database. The onboard GPS UART can be routed to the Flipper's GPIO pins for the native GPS app (Momentum firmware). Product overview and user guide: github.com/pingequalab/scout-lite.

What is ESP32 Marauder?

ESP32 Marauder is an open-source Wi-Fi/Bluetooth analysis suite, published at github.com/justcallmekoko/ESP32Marauder. On the ESP32-C5 it works across both 2.4 GHz and 5 GHz bands.

What about SigRoam?

SigRoam is an optional Flipper Zero app with a dedicated live dashboard. It is a .fap you copy to the Flipper — it is not ESP32 firmware and it is not a firmware choice on this page.

1. Leave Marauder on the Scout Lite. Do not flash SigRoam onto the ESP32.
2. Download sigroam-0.3.fap from SigRoam v0.3.
3. Copy it to SD Card/apps/GPIO/ on the Flipper.

WiGLE CSV is still written by Marauder to the Scout Lite onboard microSD, not the Flipper card.

A dedicated receive-only scanner firmware for Scout Lite is in development. It is not in the flasher. Until it ships, this page continues to write ESP32 Marauder.

Frequently asked questions

Do I have to flash the Scout Lite myself?

No. The Scout Lite ships pre-flashed with ESP32 Marauder and works out of the box — just mount it on the Flipper GPIO header. This page is for updating to a newer Marauder build or recovering the firmware.

Which board does this flash?

The Scout Lite's ESP32-C5-WROOM-1U. The ESP32-C5 is a dual-band RISC-V chip, so Marauder gets 2.4 GHz and 5 GHz Wi-Fi on the built-in radio. The onboard GPS and microSD are peripherals Marauder logs to — they are not flashed separately.

How do I put the Scout Lite into download mode?

Hold BOOT, plug in the USB-C cable while still holding BOOT, then release BOOT and click Connect. The C5's native USB doesn't yet support automatic download-mode entry in the browser flasher, so it's entered manually.

What Marauder version does this flash?

The latest stable ESP32 Marauder build for the ESP32-C5, written as three files at the C5 offsets (bootloader 0x2000, partition table 0x8000, app 0x10000).

Which browsers can flash the Scout Lite?

Chrome or Edge on desktop, Chrome on Android, or Firefox 151+ on desktop. Browser flashing uses the Web Serial API; in Firefox the first connection also adds a permission add-on. Safari and every browser on iOS cannot flash.

Can I flash SigRoam onto the Scout Lite from this page?

No. SigRoam is a Flipper Zero app (.fap), not ESP32 firmware. Do not flash SigRoam onto the ESP32. Leave Marauder on the board and copy sigroam-0.3.fap to SD Card/apps/GPIO/ on the Flipper. This page only updates or recovers ESP32 Marauder.

Is a dedicated Scout Lite scanner firmware in this flasher?

No. A dedicated receive-only scanner firmware is in development. It is not in the flasher. Shipping units stay on Marauder. When it ships it will be offered here as a browser re-flash, not a new board.
