Esp32 tracker: common questions

What microcontroller does the Esp32 tracker use?

The Esp32 tracker is built around the ESP32-WROOM, from the ESP32 family.

How big is the Esp32 tracker PCB?

The Esp32 tracker measures 7 × 7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32 tracker?

91 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32 tracker design files?

From the cnlohr/esp32_tracker repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esp32 tracker design in my own project?

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

Can I test firmware for the Esp32 tracker 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.
