Bbesc kiCad 1stAttempt
About the Bbesc kiCad 1stAttempt PCB
Bbesc kiCad 1stAttempt is an open source NXP PCB design by jakeread, published on GitHub. It is a 2-layer board, with 59 components from 19 distinct parts.
Its main chip is the teensy_3-2, from the NXP family. Other key parts include the IR2101, LM358N and LM7805. By type, the board carries 22 resistors, 14 capacitors, 7 diodes, 6 ICs, 6 transistors and 4 connectors.
It belongs with the robotics & motion designs in this gallery.
From the project
in-progress motor controller, towards accessible closed-loop control
FOCT implements 'all the bells and whistles' found in high-end robotics motor controllers (encoder feedback, BEMF & current sensing, etc) in a relatively low-cost solution. Code is written in Arduino for the Teensy Microcontroller, and is meant to be easily extensible and pick-through-able.
FOCT is in development! So is it's documentation!
Up to ~24v supply Up to 30A without a heatsink, 42 with good cooling, peaks of 60 Planned PWM in, SPI slave modes for control. Serial over USB Config / testing.

Bbesc kiCad 1stAttempt: common questions
What microcontroller does the Bbesc kiCad 1stAttempt use?
The Bbesc kiCad 1stAttempt is built around the teensy_3-2, from the NXP family.
How big is the Bbesc kiCad 1stAttempt PCB?
The Bbesc kiCad 1stAttempt has 2 copper layers and is 1.6 mm thick.
How many components are on the Bbesc kiCad 1stAttempt?
59 components, from 19 distinct parts. The full bill of materials is listed on this page.
Where can I download the Bbesc kiCad 1stAttempt design files?
From the jakeread/tesc repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Bbesc kiCad 1stAttempt 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 kiCad 1stAttempt 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.
