Overview
Root is an open-source printed circuit board by GonzaCerv, from the GonzaCerv/noah-hardware repository on GitHub, published under the MIT licence. It is a 2-layer board of 120 × 100 mm with 127 parts on 143 nets, routed with 1,351 tracks and 102 vias.
It is built around the ESP-07, MCP2551-I/SN-HG and ROB-14450, with the XL4015E1, MCP16301T-I/CHY-MS and STC3100IST among its other parts. Its parts include 33 resistors, 30 capacitors, 23 connectors, 15 ICs and 15 diodes. It belongs with the robots and motor control boards and the ESP8266 and STM32 boards of this library.

About
As a final thesis project of Electronics engineering, I decided to build a robot from scratch. All the design was made in order to build the robot with parts that can be bought in Argentina.
Take a look to the other repos related to this project:
Mechanics
The robot is made out of 3D printed parts, some parts made with 3mm laser cut and vitamins. All the parts were designed with Solidworks. You can find those parts as well as files for construction in the 3D model section.
There are 2 versions of the robot. The Noah version which uses the noah main controller board. If you want to implement your own circuit a generic version was also designed.
Electronics
The main PCB is in charge of controlling all the peripherals of the robot. You can see in the pictures a all the connectors available. Several modules were provided:
- NEO6VM - GPS
- GY91 - IMU + Compass + Barometer + Temperature sensor
- ESP07 - Wifi module
- TB6612FGN - Dual full H bridge.
At the bottom there are 4 SMPS modules installed. They are capable of delivering up to 5A per channel.
The PCB was designed with Kicad. Take a look to the PCB section.
Firmware
The STM32F407VG was choseen as the main controller of this board. It runs at 72Mhz, enough to manage the 4 main FreeRTOS tasks that are currently coded:
- PID control loop for left motor.
- PID control loop for right motor.
- Comms task: provides communication between this layer and the ROS layer.
- Power management: small task in charge of managing the energy of the power supplies.
This project uses STM32CubeIde.

Questions
How big is the Root PCB?
It measures 120 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Root use?
127 parts, built around the ESP-07, MCP2551-I/SN-HG, ROB-14450 and XL4015E1. 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 Root KiCad files?
From the GonzaCerv/noah-hardware repository on GitHub, at the commit this page was made from: the board is PCB/root.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Root design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
