In this post I am going to share all the parts you need to build your own super tiny tinyPEPPER2 4in1 Blheli_S ESC. All the following information applies to the current version 0.4 of tinyPEPPER2 (tagged as revision 0.4). If you are wondering what makes this thing so special, have a look at the main tinyPEPPER2 project page.
v0.4: (this one)
– initial openhardware release
This board uses the same outer dimensions as my tinyFISH FC: It comes in a 20x20mm package with a hole-to-hole distance of 16mm (M2). This board requires some experience with SMD soldering and requires a hot air gun or a reflow oven.
You can find the bill of materials with part references and ordering numbers for farnell and mouser on this google doc sheet.
The design files are released 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 tinyPEPPER2 ESC page). Additionally release all modifications you do and all work you derivate from this under the same license.
You can find the design in the kicad file format on my github repository. You will need a recent version from kicad. I compiled my own binaries from kicad commit hash #efdfaeb.
If you want to skip the hassle of rendering the gerber board files on your own you can simply skip this step and checkout and order the part from OSHPark.com using this Link (rev 0.4). They offer a really great quality for a ridiculous low price (it is $7 for three copies!).
Placement & Connections
You can use the following diagrams for the component placement. See my github repository for the full resolution files in SVG format.
Now it is time to build your own! This page has all the information you need to build your own tinyPEPPER2 ESC. Sure, this requires very fine pitch soldering, but if you have some experience with SMD soldering give it a try! If this sounds too complicated for you, don’t worry, FuriousFPV is selling this ESC. I am quite sure several other places will pick this design up and sell it soon.
Please check the main tinyPEPPER2 project page for updates. I will try to keep an updated list of who sells this ESC. If you wish, drop me an email and I will add you to the list.
If you have built any of my stuff I would be happy to see and hear how it turned out for you — send me an email!
