I’m a software guy, but interested in IoT devices. I know almost nothing about the physical aspects of electronics. I have purchased a Sonoff ESP2866-based switch that I’d like to flash with different software, and I’ve looked at the following video on how to do it

I’ve managed to solder the pins to the board, but I don’t know what interface to buy to connect the pins to the USB interface on my computer (a Macintosh, by the way). Any guidance will be greatly received. S t u a r t .
