About the ESP32 test board

ESP32 test board is an open source PCB design by JCastel358, published on GitHub. It is a 2-layer board measuring 86 × 103 mm, with 40 components from 13 distinct parts.

Other key parts include the AMS1117 and LTV-847S. By type, the board carries 24 resistors, 7 capacitors, 3 transistors, 2 ICs and 1 diode.

From the project

code for industrial automation process

Routed engineering prototype candidate. Not a fabrication release.

This separate project replaces the supplied ESP32 carrier while preserving the original files in sourcereference/`. Its required behavior is that the upstream USB switch starts and stops the complete rig, including both HeyFuture LiFePO4 6.4 V, 6 Ah battery domains, with the ADC protected throughout startup and shutdown. The emitter maximum stated current is 200 mA. Component selection is independent of the IRLB8748s available for the earlier perfboard idea.

ESP32 test board: common questions

How big is the ESP32 test board?

The ESP32 test board measures 86 × 103 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 test board?

40 components, from 13 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 ESP32 test board design files?

From the JCastel358/Eltec406mca 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 ESP32 test board design in my own project?

The repository has no license, so all rights stay with JCastel358. Use it as a reference, and ask the author before reusing the design.
