About the Unni smartification c6-10.99-constraints PCB

Unni smartification c6-10.99-constraints is an open source ESP32 PCB design by lk-ek, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 19 × 18 mm, with 66 components from 36 distinct parts.

Its main chip is the ESP32-C6-MINI-1-N4, from the ESP32 family. Other key parts include the MCP73831, TPS63031 and TPS613222A. By type, the board carries 27 resistors, 19 capacitors, 7 connectors, 5 transistors, 4 ICs and 4 diodes.

It belongs with the sensors, iot & wireless and power & battery designs in this gallery.

From the project

An esp32-c3 based passive data sniffer for Unni CO2 sensor devices

Target: KiCad 10.99 nightly or newer. The current manufacturing master uses a 4-layer stackup and native KiCad 10.99 geometric constraints.

This repository contains two physical PCBs in one KiCad PCB file so cross-board connectivity remains visible while routing. Placement and routing are still work in progress; the schematic and power architecture are substantially defined and covered by reproducible connectivity/SPICE checks.
