Overview
UpgradePlan is an open-source printed circuit board by Joni0131, from the Joni0131/rospCar repository on GitHub. It is a 2-layer board of 120 × 110 mm with 31 parts on 68 nets, routed with 291 tracks and 4 vias.
It is built around the L293D and C945. Its parts include 14 resistors, 5 ICs, 3 transistors, 3 connectors and 2 diodes. It belongs with the ESP32 boards of this library.
Main components

This repository contains the whole redevelopment of an old RC car.
To change the control system to an esp32 and a ROS communication with the computer to potentially implement a SLAM algorithm.
Work progression
I structured my work in the following four steps. Those are shortly discussed on this page for more detailed information on each step please correspond to each designated page.
1. Old System
The first step of the redevelopment process consists of understanding and checking the currently used electronics. As well as their functionality.
2. Planning
In the second phase, I chose the requirements for the new car, ordered parts that fulfill those requirements as well as designed the new circuit diagram.
3. ESP-32
The third step is considered the heart of the hardware development process. Here I define the functional requirements for the esp-32 and implement those decently.
4. Brain
Last but not least I design the other side of the communication and control algorithm for this project on the computer. The computer software is calculating the movements of the car and is using the sensor data to do this. Furthermore, it will be using a SLAM algorithm to map the whole area and it will be possible to go to certain locations easily.

Questions
How big is the UpgradePlan PCB?
It measures 120 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UpgradePlan use?
31 parts, built around the L293D and C945. 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.
Where can I download the UpgradePlan KiCad files?
From the Joni0131/rospCar repository on GitHub, at the commit this page was made from: the board is upgradePlan/circuit/circuit.kicad_pcb and its schematic oldSystem/initialSystem/initialSystem.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UpgradePlan design in my own project?
Its repository states no licence, so its author keeps all rights: ask Joni0131 before reusing the design.
