It have BOM, Custom PCB, 3D printed Enclosure, buttons and suport. Download All files(.stp) from Enclosure printable folder and print 'em > It uses M2 screw everywhere > For part link please download .odf not .csv > In assembly u may see the MCU as colliding with PCB dw! it just cz I can't remove the header pins. :lollll: !alt text !alt text !alt text !alt text !alt text !alt text !alt text ### Instructions First comes the MCU U hve to castellated solder it on top of the board or can use very low height header pins

HUGINN: common questions

What microcontroller does the HUGINN use?

The HUGINN is built around the ESP32-S3-DEVKITC-1U-N8R8, from the ESP32 family.

How big is the HUGINN PCB?

The HUGINN measures 37.9 × 69.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HUGINN?

35 components, from 27 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 HUGINN design files?

From the basic-bitch-foundation/HUGINN 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 HUGINN design in my own project?

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

Can I test firmware for the HUGINN 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.
