Nitrokey lora hardware: common questions
What microcontroller does the Nitrokey lora hardware use?
The Nitrokey lora hardware is built around the ESP32-D0WD, from the ESP32 family.
How big is the Nitrokey lora hardware PCB?
The Nitrokey lora hardware measures 40 × 17.6 mm, has 4 copper layers and is 1 mm thick.
How many components are on the Nitrokey lora hardware?
87 components, from 54 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 Nitrokey lora hardware design files?
From the Nitrokey/nitrokey-lora-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Nitrokey lora hardware design in my own project?
The repository has no license, so all rights stay with Nitrokey. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Nitrokey lora hardware 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.
