Bbesc: common questions
What microcontroller does the Bbesc use?
The Bbesc is built around the teensy_3-2, from the NXP family.
How big is the Bbesc PCB?
The Bbesc measures 110.5 × 82.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Bbesc?
79 components, from 25 distinct parts. The full bill of materials is listed on this page.
Where can I download the Bbesc design files?
From the jakeread/bbesc repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Bbesc design in my own project?
The repository has no license, so all rights stay with jakeread. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Bbesc 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.
