Simple breakout board for using TMC5130 motor driver chip
Parts:
U1 TMC5130 - Digikey 1460-1126-1-ND
U2 5V 500mA LDO (optional) ONSemi MC78M05CDTRKG - Digikey MC78M05CDTRKGOSCT-ND
C1 22nF 50V+ 0603 - Digikey 1276-6534-1-ND
C2,C3,C5 0.1uF 50V+ 0603 - Digikey 1276-1936-1-ND
C4 4.7uF >5V 0603 - Digikey 587-1441-1-ND
C6,C7 1uF >5V 0603 - Digikey 587-1248-1-ND
C8 0.1uF >5V 0603 - Digikey 490-1532-1-ND
C9 100uF 50V - Digikey 50PEV100M10X10.5CT-ND
R1,R2 0.1 Ohm 0.5W 1% 1206 - Digikey 1276-6160-1-ND
R3 2.2 Ohm 0603 - Digikey 311-2.2GRCT-ND
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.

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.
