About the Robot PCB
Robot is an open source NXP PCB design by sidstuff, published on GitHub under the MIT license. It is a 2-layer board measuring 63 × 68.5 mm, with 71 components from 35 distinct parts.
Its main chip is the Teensy4.0, from the NXP family. Other key parts include the ADXL343, TPS610997DRV, MPU-6050, Inverter_Schmitt_Dual and L293D. By type, the board carries 29 resistors, 12 capacitors, 11 connectors, 9 ICs, 4 transistors and 2 diodes.
It belongs with the robotics & motion and power & battery designs in this gallery.
From the project
A KiCad PCB for an obstacle avoiding robot.
A common type is the micromouse, a small robot which tries to solve a maze. I.e., it tries to reach the center of a maze made up of a 16×16 grid of cells, each 180 mm square with walls 50 mm high.
While picking parts, ensure that the voltage/current/power ratings of componenets are not exceeded. Also, lithium cells have a nominal voltage of 3.7V (although it can go up to 4.2V when fully charged, and can be discharged until 3V), so their batteries are going to be multiples of the same.

Robot: common questions
What microcontroller does the Robot use?
The Robot is built around the Teensy4.0, from the NXP family.
How big is the Robot PCB?
The Robot measures 63 × 68.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Robot?
71 components, from 35 distinct parts. The full bill of materials is listed on this page.
Where can I download the Robot design files?
From the sidstuff/robot repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Robot design in my own project?
Yes, under the terms of its MIT license, which sidstuff chose for the repository.
Can I test firmware for the Robot without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
