ESP32 CSI WIFI NODE: common questions

What microcontroller does the ESP32 CSI WIFI NODE use?

The ESP32 CSI WIFI NODE is built around the ESP32-S3-WROOM-1U, from the ESP32 family.

How big is the ESP32 CSI WIFI NODE PCB?

The ESP32 CSI WIFI NODE measures 60 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 CSI WIFI NODE?

30 components, from 28 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 CSI WIFI NODE design files?

From the swayerloren/KICAD_ENGINE 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 CSI WIFI NODE design in my own project?

Yes, under the terms of its MIT license, which swayerloren chose for the repository.

Can I test firmware for the ESP32 CSI WIFI NODE 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.
