Hi, I’ve started on my next board build.
This is using:
- DRV8316 (engineering sample)
- ESP32 PICO V3
- MA702 Encoder
Here’s the KiCad render:
And the board in real life:
The idea is that the magnet would be glued to the end of the motor shaft, and the driver board would be attached to the motor - with washers or a 3d printed spacer.
I have one issue so far with how I’ve setup the DRV’s sleep pin, but I can work around this for testing.
This is a 2 layer board, and this time I’ve used HASL instead of ENIG, and it worked well.
Total BOM cost in quantities of 10 is around $13.
Now I’ll have to look at @runger 's code to get SimpleFOC running!
