My previous post was about how to receive serial signal data from a (pre-bound) SPM9645 remote receiver with RPi's GPIO. Now I will show you how to control an ESC based on the received remote control data using an Adafruit 16-Channel 12-bit PWM driver. Maybe this information can be useful to you or it can save you some time. I am happy for…Continue

- When will ESCs be readily available with SimonK firmware pre-flashed?
- When will some easily obtainable ESCs support I2C, so that flight controllers can read motor status?
HobbyKing has provided the answer, with the newly introduced AfroESC. It's licensed from both SimonK and timecop.
Hereby my project, I wanted to build a quadrocopter to learn more about system control and brushless motor and because it is cool. To target also was to make it without as little wires as possible and that is why I made a…Continue
We have been working lately with Jason.J and few other people to create first real Open Source ESC that is based on STM32 RISC processors. Just moment a go courier delivered first PCBs to my desk here at jDrones and we are thrilled to see how they start perform after assembly has done for these.
OpenESC pcbs are 35 x 25mm and 4 layers PCBs. Power range…Continue

Most of the pro multicopter set-ups have feedback from the ESCs so the controller knows the status of the motors. This is useful for all kinds of reason including:
1. debugging the causes of crashes - the controller could log when a motor has stopped running.
2. allows faster and better reaction to a motor failure perhaps saving you from a crash at least for…Continue
Development: New power distribution board
Some of you might already seen this board on Open-source ESC development post several days ago and some not. As…Continue
It was a productive weekend: MP up and running on my shop PC, aircraft firmware loaded into APM2, radio connections troubleshot and calibrated, Wow! There's my house with a graphic quad hovering over it! (I am not worried about giving away my coordinates. Come on by but call first, please.) After…Continue
I had a request to provide information on how I implemented an ESC fail safe on my quadcopter and posted a small image of the process under the ArduCopter 2.5 firmware thread. Since I suspect there may be a more general interest in this, I'm posting a blog segment on this fail safe.
Above is an image of the process.
Also, here's a pdf…Continue
My name is Adam Miłosz and I'm on of the guys working on Rock ESC.
Just to give you the idea of the ESC that we want to develop, here are the highlights of the planned features:
• super fast motor response time,
• overcurrent protection,
• open source software,
• high current handling -…
