The Silk FC schematic is finished and the PCB is 70% done.
Here are some screenshots:
There is a bit of wiring acrobatics with the PWM connector as I couldn’t find an eagle 6×3 header so I improvised one from 3 2×3 headers… Ugly but it works.
As soon as they are done I will put them on github.
The board is 2 layers only and has the specs from my last post.
I intend to add a footprint for a RFM22B as well as the RF4463F30 so I can choose which to use, in case one of them has issues.
The board should work in both single-imu-baro more and also in dual-imu-baro.
I got 2 MPU9250 and MS5611 from my previous Drotek 10 DOF boards with a bit of hot air.
I’m really curious how it will end up as this is my first SMD board and especially my first QFN package. The MPU is really really tiny – like 2 square millimeters.
