#240 USB-to-Serial Isolator ⚡ Protect your USB sockets ☠

Protect your USB sockets with this bidirectional USB to Serial isolator ► JLCPCB Only $2 for PCB Prototype any colour ► More details in my GitHub for this video: ► You can now support me by buying me a coffee! This project was inspired by an idea/project by Tim Blythman in the March 2022 edition of Practical Electronics. More details on this excellent magazine here: I have modified the circuit slightly and created a custom PCB for my own use which I share here.
