Winter projects 2018, servo drivers, brushed motor controllers, silabs based esc's and some 32 bit speed controllers FOC and back emf. Will post about each one in the future -

A 2 layer 32 bit stm32f051 speed controller dev board. tested and working. Is pin compatible to wraith32. The programming pins and such are all broken out to pin headers. If any one want one to play around with let me know.

Total of 22uf x 8 = 176uF capacitance , seems fine for an 1306 motor on 2s/3s. -

I use a heat gun for the nfets there are no legs. -

I like this FC/PDB layout the best, not fancy but it sure is fast to wire up and transfer between frames. -

Pay attention to the datasheet of the P-fet especially the pinout. That's why its represented in the schematic and layout as an N-FET. The mosfets q5,q7,q9 should just be 2n2222a sot23 transistors.

Forget some resistors ? no problem just stick them into the trace sideways. -

My esc's are so compact they don't even have pads to solder the motors on to. -

Got this far before I realized there was no possible way to upload a program to this board. -

Apparently you need an interrupt pin for the gyro. -

Maybe if I make the wire black no one will notice. -

Dead short between power and ground ? ..no worries .. it sorts itself out first time you plug it in. -

This one actually works
