From the project

The KiCAD Design Files for Georgia Tech RoboJackets RoboCup Small Size League's Electrical Systems

This board serves as a proof of concept (PoC) for the design of control board v4.0

The main components contained in this board are:

- Xilinx Spartan 7 25T FPGA - QSPI Flash Memory - CMOS Clock - USB/JTAG/UART Interface - 18.5V, 5V, 3.3V, 1.8V, 1.0V Voltage Levels - 3 Phase Motor Driver

This is the main controller that coordinates the 5 different motor drivers. It interfaces the main microcontroller via SPI and controls the 3 phase gate drivers.

Motortester v2.0: common questions

What microcontroller does the Motortester v2.0 use?

The Motortester v2.0 is built around the Teensy4.1, from the NXP family.

How big is the Motortester v2.0 PCB?

The Motortester v2.0 measures 105.9 × 88.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Motortester v2.0?

76 components, from 33 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Motortester v2.0 design files?

From the RoboJackets/robocup-pcb repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Motortester v2.0 design in my own project?

Yes, under the terms of its Apache-2.0 license, which RoboJackets chose for the repository.

Can I test firmware for the Motortester v2.0 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.
