Dog tracker routed: common questions

What microcontroller does the Dog tracker routed use?

The Dog tracker routed is built around the ESP32-S3-WROOM-1-N4, from the ESP32 family.

How big is the Dog tracker routed PCB?

The Dog tracker routed measures 30 × 23 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dog tracker routed?

27 components, from 19 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 Dog tracker routed design files?

From the jonathanleahy/lora repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Dog tracker routed design in my own project?

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

Can I test firmware for the Dog tracker routed 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.
