Pami n20 Chimique: common questions
What microcontroller does the Pami n20 Chimique use?
The Pami n20 Chimique is built around the ESP32_DevKit_V1_DOIT_30GPIOs, from the ESP32 family.
How big is the Pami n20 Chimique PCB?
The Pami n20 Chimique measures 67.4 × 50.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pami n20 Chimique?
18 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pami n20 Chimique design files?
From the Rami-Troudi/Electrique-Eurobot-IEEE-INSAT-2026 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pami n20 Chimique design in my own project?
The repository has no license, so all rights stay with Rami-Troudi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pami n20 Chimique 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.
