About the Sensors PCB
Sensors is an open source ESP32 PCB design by lukokemba2, published on GitHub. It is a 2-layer board measuring 90 × 90 mm, with 9 components from 8 distinct parts.
Its main chip is the PC817, from the ESP32 family. Other key parts include the LM1084-5.0, MQ-135, NE555P and GPS NEO 8M. By type, the board carries 5 ICs, 2 connectors and 2 resistors.
It belongs with the sensors, rf & radio and robotics & motion designs in this gallery.

Electrical CAD and firmware
2. Open the project in your IDE. 3. Install the required libraries listed in the dependencies section of the code. 4. Select the correct board and port in your IDE. 5. Upload the code to your microcontroller.
- Inputs: The controller takes crisp inputs from the sensors (e.g., "distance to target" from GPS, "angle error" from IMU). - Fuzzification: These crisp values are converted into fuzzy values like "Close", "Medium", "Far" or "Small Error", "Large Error". - Inference: A set of rules (e.g., "IF distance is Far AND angle error is Large, THEN deploy control surface a LOT") is applied. -…

Sensors: common questions
What microcontroller does the Sensors use?
The Sensors is built around the PC817, from the ESP32 family.
How big is the Sensors PCB?
The Sensors measures 90 × 90 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Sensors?
9 components, from 8 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 Sensors design files?
From the lukokemba2/Comeback-CanSat 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 Sensors design in my own project?
The repository has no license, so all rights stay with lukokemba2. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Sensors 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.
