I ordered 4 boards total, and it took about 4 weeks. (Note: this only reflects the cost of SMD parts, not the through-hole parts like the MOSFETs). Approximate cost was $190 for PCB and the parts to make the complete board. Again this is not a tutorial so I wont go through all the steps but I loaded the comma separated values into excel to massage all the lists into the correct format. Kicad makes lists of all the parts, and it creates a 'centroid' file, which tells the factory how place all the parts in their correct location. Instead I used a Printed Circuit Board Assembly (PCBA) service. NOTE: as mentioned by Galp's build post ( ) be sure to remove U7 and bridge the lines between pins.Īt any rate, the size of some of the parts on the G2 are less than 1mm, and you may be more brave than I but assembly involve simply way too many parts. If you want to try making your own board be prepared for the fact that parts always go out of date, and you either have to find a part that fits in the same footprint as before, Another problem which was his original 8MHz crystal was not obtainable, but I was able to use: ECS-80-18-30B-AGN-TR which fit on the footprint of his design exactly. Start with this list and painstakingly make sure that all of the parts are still available. My favorite is Tools->edit symbol fields in Eeschema. Kicad has a bunch of menu functions that help you with reviewing the parts list. I downloaded his files, loaded them into kicad, and checked all the parts to make sure that I could create a list from, the electronics supplier. I'm gonna assume you know what youre doing. This is not a step by step tutorial, and the skill levels required are you at a minimum have to know about electronics, using Kicad printed circuit board (PCBs) software, ordering PCBs, and PCB assembly.ġ00v, 400A. So, the following is a description of my experience of getting a BESC-G2 into my hands for testing. The cool thing about VESCs is comes with a very nice interfaceĪnd if you have a functional VESC, there are some nice instructional videos on using the VESC-tool. VESCs can be found in abundance on amazon, search under that name. Galp publicized development of the G2 over here on the VESC project site: The BESC is a variant of the Vedder ESC which originally was an open source ESC project which has been partially commercialized.

Galp is incredibly prolific based on his posts at his blog:Īnd he made at least two versions of the BESC:Īnd has some comments on that page about making a third version.Īnd he provided a write up of the G2 here: The designer of big(?) ESC (BESC) goes by user name galp. This write up is an overview of building an open source electronic speed controller (ESC) that was originally posted here: viewtopic.php?f=30&t=97765
