About the Skimmer-Detector-PRO PCB

Skimmer-Detector-PRO is an open source ESP32 PCB design by planmarks, published on GitHub. It is a 2-layer board measuring 84.2 × 49.8 mm, with 65 components from 38 distinct parts.

Its main chip is the ESP32-WROOM-32E, from the ESP32 family. Other key parts include the AP7361C-33E, MCP73833-FCI/MF, DM-OLED096-636, FS8205A and DW01A. By type, the board carries 20 resistors, 15 capacitors, 10 ICs, 7 switches, 7 diodes and 3 transistors.

It belongs with the iot & wireless, power & battery and rf & radio designs in this gallery.

From the project

ESP32 Based Wireless Skimmer Detector

A pocket-sized, dual-radio detector for wireless ATM & card-skimmer modules.

Hermes PRO is the next-generation successor to Hermes v0.1a. Where the original used a single ESP32 to scan Bluetooth Classic only, PRO pairs two radios — an ESP32-C5 (Bluetooth LE 5 + dual-band Wi-Fi 6) and an ESP32-WROOM-32E (Bluetooth Classic / BR-EDR) — so it can flag the widest possible range of skimmer hardware, old and new, from a single handheld device.

Skimmer-Detector-PRO: common questions

What microcontroller does the Skimmer-Detector-PRO use?

The Skimmer-Detector-PRO is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the Skimmer-Detector-PRO PCB?

The Skimmer-Detector-PRO measures 84.2 × 49.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Skimmer-Detector-PRO?

65 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Skimmer-Detector-PRO design files?

From the planmarks/Skimmer-Detector-PRO repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Skimmer-Detector-PRO design in my own project?

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

Can I test firmware for the Skimmer-Detector-PRO 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.
