ESP32 CYD Field Guide
Choose the toolkit that fits your bench.
This build starts with the ESP32-2432S028R, often called the 2.8-inch Cheap Yellow Display or CYD. Pick ESP32 Marauder for a focused wireless toolkit, or Bruce firmware for a broader modular ESP32 setup.
Marauder Firmware
Focused wireless visibility
ESP32 Marauder keeps the touchscreen build centered on Wi-Fi and Bluetooth scanning, channel visibility, packet monitoring, and supported capture tools for your own lab or authorized assessment work.
Bruce Firmware
A broader ESP32 toolkit
Bruce is the flexible option for people who want supported wireless discovery tools, general device utilities, Micro-SD workflows, and room to explore additional compatible hardware later.
Configured To Order
Your finish, your field unit
Select a case color, choose a plain or painted finish, and add a stencil if you want one. Each enclosure is finished by hand, so the distressed pattern on every TraceFinish CYD build is unique.
Does the ESP32 CYD arrive ready to use?
Yes. The ESP32-2432S028R arrives assembled in your selected enclosure with your chosen firmware prepared and bench-tested before shipment.
Can I choose ESP32 Marauder or Bruce firmware?
Yes. Choose either firmware in the configurator above. The information buttons next to each option explain the out-of-box focus of both builds.
Can I order a plain case without paint or a stencil?
Yes. Select No paint and the configurator will automatically disable stencil choices for a clean plain enclosure.
What is authorized use?
Wireless assessment features should only be used on networks and devices you own or have explicit permission to test.

Arrived quickly and with the latest version loaded. Seller also confirmed the Miady 5000mAh in one of the photos was a good fit with the included case, so this is a great way to snag a ready-to-go handheld Marauder.
Excellent quality and shipped very quick.

After having a bad experience with another seller I was really comfortable and will for sure buy again if needed.

This was a flawless transaction - above average, really. I had several questions, before purchase, after purchase, and after arrival, and they were all answered quickly and completely. Colin was helpful, understanding, and thorough with the information shared. The device worked flawlessly straight out of the box which was packaged very well. It was padded and the components were zipped up in anti-static bags. I will definitely do business with this shop again!

Great communication, incredibly quick shipping, and item was in pristine condition upon arrival. Would recommend 10/10.
Most unique case for the ESP32 CYD (2432S028R) I've seen. Colin had great communication. Very pleased.
