Open Source ESC Developed for Longboard Commute

Open Source ESC Developed for Longboard Commute

For electric and remote control vehicles – from quadcopters to electric longboards – the brains of the outfit is the Electronic Speed Controller (ESC). The ESC is just a device that drives a brushless motor in response to a servo signal, but in that simplicity is a lot of technology. For the last few months, [Ben] has been working on a completely open source ESC , and now he’s riding around on an electric longboard that’s powered by drivers created with his own hands. The ESC [Ben] made is built around the STM32F4, a powerful ARM microcontroller that’s able to do a lot of computation in a small package. The firmware is based on ChibiOS , and there’s a USB port for connection to a sensible desktop-bound UI for adjusting parameters. While most hobby ESCs are essentially black boxes shipped from China, there is a significant number of high performance RC pilots that modify th...
