About the Mold Scout PCB

Mold Scout is an open source ESP32 PCB design by jayis1, published on GitHub. It is a 2-layer board measuring 95 × 52 mm, with 7 components from 7 distinct parts.

Its main chip is the STM32G474RET6, from the ESP32 family. Other key parts include the ESP32-C3-MINI-1, AD8331ARZ and LMG1210RVRT. By type, the board carries 4 ICs, 2 connectors and 1 LED.

It belongs with the iot & wireless and sensors designs in this gallery.

From the project

Novel SoC device designs: blueprints, schematics, firmware, and docs — a new invention every 24h.

Mold Scout is a practical field tool built around the ESP32-S3-WROOM-1-N8. It is meant for home inspectors, remediation crews, facilities teams, landlords, and energy auditors who need more than a simple pin moisture meter but less bulk and cost than a full thermal camera plus separate IAQ kit.

- non-contact capacitive dielectric sensing through paint, drywall, and thin panel materials - 32×24 thermal imaging to find cold spots and wet thermal anomalies - ambient temperature / humidity for dew-point analysis - VOC / gas sensing to flag stale damp cavities and microbial off-gassing trends -…

Mold Scout: common questions

What microcontroller does the Mold Scout use?

The Mold Scout is built around the STM32G474RET6, from the ESP32 family.

How big is the Mold Scout PCB?

The Mold Scout measures 95 × 52 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mold Scout?

7 components, from 7 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 Mold Scout design files?

From the jayis1/SoC-Device-Inventions 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 Mold Scout design in my own project?

The repository has no license, so all rights stay with jayis1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Mold Scout 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.
