Hi there,
I've done some research and also bricked my Arduino Uno 3 times spending hours to fix it.
I have an Arduino Uno R3 and a TMC2209 driver.
How I have connected it:
TMC2209 - UNO R3
DIR - Pin5
STEP - Pin4
VIO - 5v
GND - GND
VMOT - Power Supply 12v +
GND - Power Supply 12v -
I'm using this here except he shows to put the STEP pin into 0/1 pin
What does "bricked" mean? Describe what happened.
Tell us something about your motor's voltage and current rating.

I have a good 12v power supply (similar to laptop chargers) do I still need a ESR Capacitor?
What did you have to do to unbrick your UNO?
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
Some pictures of your project would also help.
Thanks.. Tom..
