LegRobotBoardTeensy: common questions

What microcontroller does the LegRobotBoardTeensy use?

The LegRobotBoardTeensy is built around the TEENSY4.1, from the NXP family.

How big is the LegRobotBoardTeensy PCB?

The LegRobotBoardTeensy measures 178.2 × 111 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LegRobotBoardTeensy?

154 components, from 20 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 LegRobotBoardTeensy design files?

From the 01binary/str1ker 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 LegRobotBoardTeensy design in my own project?

The repository has no license, so all rights stay with 01binary. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LegRobotBoardTeensy 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.
