LoRa tracker: common questions

What microcontroller does the LoRa tracker use?

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

How big is the LoRa tracker PCB?

The LoRa tracker measures 116.3 × 114.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LoRa tracker?

53 components, from 33 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 LoRa tracker design files?

From the bendelathouwer/asset-tracker 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 LoRa tracker design in my own project?

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

Can I test firmware for the LoRa 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.
