This is a sneak preview, in order to save you some time I will now share the board design and the bill of materials with you. You can go ahead and order the parts right now, by the time they arrive at your place I will have published all details for you to build your own.
This is licensed under the CERN open hardware license v1.2. Before using the design files for commercial projects please make sure that you read and understand this license! You can use the files for your projects, just make sure to give proper credit (by e.g. linking to the tinyPEPPER ESC page). Additionally release all modifications you do and all work you derivate from this under the same license.going to be open hardware.
Compared to the tinyFISH FC, this is a piece of cake. It is quite easy to solder when you have access to the right tools. Don’t hesitate, just give it a try!
Enough said, here are the links you have been waiting for (probably too) long:
- order tinyPEPPER v0.3 on OSHPark ($3 for three copies, make sure to use 0.8mm PCB with 2Oz copper!)
- bill of materials with part numbers from farnell and mouser
You will need no special programmer for this, any usb2serial converter will do. The EFM8 devices come with a bootloader and I wrote a small python script that will do the flashing. I will publish a tutorial soon.
To those who ordered the v0.2 boards from oshpark some days ago: Don’t worry, your boards are fine. The only change to v0.2 is the reordering of the motor phase tabs to the same side.
