gusmanb/logicanalyzer
24 channel, 100Msps logic analyzer hardware and software

Self-balancing two-wheeled robot powered by an ESP32 and MPU6050 IMU, featuring custom PID control, Kalman filtering, and a wireless Bluetooth interface. Designed with KiCad
SelfStandingRobot is an open-source printed circuit board by Jamane92, from the Jamane92/Self_Balancing_Robot repository on GitHub. It is a 2-layer board of 72.1 × 79.3 mm with 29 parts on 51 nets, routed with 100 tracks and 4 vias.
Its parts include 7 capacitors, 7 resistors, 7 connectors, 1 IC and 1 diode. It belongs with the robots and motor control boards of this library.

Voici la section PCB du projet, j'y expose l'intégralité des documents nécessaires pour récupéerer le projet. Ce projet avait avant tout pour but de m'initier à la création de mon tout premier PCB, il n'utilise que des composants THT ou module complet que j'ai implémenté sur le PCB. Voici à quoi ressemble la 3D de mon PCB :
--ENGLISH--
Here is the PCB section of the project; I have provided all the necessary documents to replicate it. The primary goal of this project was to learn how to design my very first PCB; it uses only through-hole (THT) components or complete modules that I mounted onto the board. Here is what the 3D view of my PCB looks like:

Et voici le routage, gardez à l'esprit que c'est mon tout premier PCB, avec que des composants THT, sans copper zone pour la puissance par exemple, sans plan de masse correct garantissant des EMI basses et une intégrité du signal, même si sur ce genre d'application, on est loin d'avoir ce genre de problème. L'important pour moi à ce moment là, c'était que ca marche, pour me donner la confiance d'aller sur des projets plus poussés.
--ENGLISH--
And here is the routing; keep in mind that this is my very first PCB, using only through-hole components, with no copper pour and no proper ground plane to ensure low EMI and signal integrity—though for this type of application, such issues are far from being a concern. The important thing for me at that point was for it to work, to give me the confidence to take on more advanced projects.

It measures 72.1 × 79.3 mm and has 2 copper layers, 1.6 mm thick.
29 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Jamane92/Self_Balancing_Robot repository on GitHub, at the commit this page was made from: the board is PCB/SelfStandingRobot.kicad_pcb and its schematic PCB/SelfStandingRobot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Jamane92 before reusing the design.
