ESP32 Wireless Debug Probe Kit - JTAG/SWD over WiFi for ARM MCUs
ESP32 Wireless Debug Probe Kit - Cut the Cable While Debugging ARM Microcontrollers
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Debugging ARM Cortex-M boards usually means being tethered to a USB cable. This kit turns an ESP32 into a WiFi-connected JTAG/SWD probe that talks to OpenOCD on your PC, giving you the freedom to test code from across the room. Ideal for embedded developers, IoT prototyping, and robotics projects where physical access is cumbersome.
What You'll Build
A compact, self-contained wireless debug adapter with an OLED status screen. You'll flash the ESP32 with custom firmware that bridges OpenOCD commands over WiFi, connect it to your target (STM32, nRF52, etc.), and experience a seamless debugging workflow without cables. The enclosure makes it durable for field testing or repeated lab use.
What You'll Learn
- Configuring ESP32 as a transparent WiFi-to-JTAG bridge using OpenOCD's remote protocol
- Wiring JTAG/SWD signals with proper 33? termination resistors and level management
- Designing a stable power supply with an LM2596 buck converter for clean 3.3V and 5V rails
- Soldering through-hole components on a prototype board and assembling an ABS enclosure

Who This Kit Is For
B.Tech ECE and EEE students diving into advanced embedded systems, IIT/NIT/VIT/BITS participants building hardware for the Smart India Hackathon, and professional firmware developers who need a reliable wireless debug station. You should be comfortable with soldering and C/C++ toolchains.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI companion through the QR code, or message us on WhatsApp. We'll walk you through the exact step you're on.
Which ARM targets does this work with?
Any Cortex-M3, M4, M7, or similar that supports JTAG/SWD via a standard 20-pin header. Tested extensively with STM32F4 and nRF52 series.
Can I use this on a university lab Wi-Fi network?
Yes. The ESP32 connects to the campus Wi-Fi and uses OpenOCD's TCP interface, which works through firewalls with the right port setup.
Do I need prior soldering experience?
Soldering is part of the kit, but the AI companion includes close-up photo guidance for each joint. A good soldering iron is included, so first-timers can build confidence.
ESP32 emulates JTAG/SWD over WiFi. Connects to OpenOCD on PC to debug ARM Cortex-M targets wirelessly.
