About the IP Sniffer PCB

IP Sniffer is an open source ESP32 PCB design by Stevemwa, published on GitHub. It is a 4-layer board measuring 50 × 50 mm, with 60 components from 29 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the AMS1117, IRLML2502TRPBF, CH340C and W5500. By type, the board carries 27 resistors, 19 capacitors, 6 ICs, 4 connectors, 1 crystal and 1 switch.

It belongs with the iot & wireless and dev boards & breakouts designs in this gallery.

IP Sniffer: common questions

What microcontroller does the IP Sniffer use?

The IP Sniffer is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the IP Sniffer PCB?

The IP Sniffer measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the IP Sniffer?

60 components, from 29 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the IP Sniffer design files?

From the Stevemwa/PCB_Designs repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the IP Sniffer design in my own project?

The repository has no license, so all rights stay with Stevemwa. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the IP Sniffer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
