R4,R5,R6 DNP (0Ohm/jumper can be used to pick which CS line to use after cutting trace)

Usage:

The TMC5130 datasheet describes all the registers and how to communicate with the chip - Near the end it provides a startup sequence which was easy to program and was a good starting point for other software to control it.

BMI055 Breakout

2 layer board of 0.70x0.80 inches (17.78x20.32 mm).
Shared on August 16th, 2014 20:59.

Simple breakout of partial BMI055 functionality that I made to integrate this part into another project

C1: 1uF

C2: 0.01uF

R1: 10k (interrupt line pullup)

The capacitor values aren’t critical, but this chip should have some bypass cap installed for local power stability.
