From the project

I want to create an ai assistant . Now a days am very much thinking about it . Then I got an idea to create a ai assistant fully offline. Running fully offline model

Assistant: common questions

What microcontroller does the Assistant use?

The Assistant is built around the TP4056, from the ESP32 family.

How big is the Assistant PCB?

The Assistant measures 80.7 × 40.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Assistant?

25 components, from 16 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 Assistant design files?

From the emmanuelprakash177-gi/RPI-AI-ASSISTANT 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 Assistant design in my own project?

The repository has no license, so all rights stay with emmanuelprakash177-gi. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Assistant 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.
