Anti Static Mat Set with Wrist Strap and Grounding Wire Electrostatic Discharge Protection for Electronics Repair

Depends a lot on you, your clothing / footwear and where you work with the board. If you don't tend to get static shocks when you touch stuff then you probably don't need to worry. If you want to do it right then you should get an anti-static mat and wristband and earth them both. Something like: https://www.amazon.com/Electrostatic-Discharge-Protection-Anti-Static-Electronics/dp/B07NPNTQJR, you can clip it to something connected to earth, or you can also get a wall plug that only has the earth pin and use that, like in this image: https://www.bondline.co.uk/wp-content/uploads/2019/08/VBLMworkstation.jpg
