Wakeup buddy

A desk companion cube that takes over the things you unlock your phone for, so you have no reason to pick it up.

This is my project that I got an idea for when my phone's alarm went off. I always tend to use my phone a little bit in bed when I wake up. I thought I needed my phone to wake me up but then I thought of a product that replaced all the "utility" items your phone could do but without the distractions. I used screentime apps before but they always make it in fingers reach to disable it. Amigo takes the other approach. Instead of locking the phone down, it takes over the jobs you…

Amigo main: common questions

What microcontroller does the Amigo main use?

The Amigo main is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Amigo main PCB?

The Amigo main measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Amigo main?

35 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 Amigo main design files?

From the Ethan2502/Amigo 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 Amigo main design in my own project?

The repository has no license, so all rights stay with Ethan2502. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Amigo main 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.
