For some reason I was sure I’d be able to flash the Arduino with something I already have, but it specifically needs a usbasp? I’ve got USB-UART, JTAG, and ST-Link. A quick Google search said none of that would help

And it looks like all my Arduinos got lost during the moves.

Google it — you can make one out of another Arduino, an ESP, an STM, or pretty much anything, there are tons of ready-made firmwares. You can also read up on your JTAG, maybe it has SPI too.

Got it, I’ll look into ESP32 then.

I’ve personally flashed it with that, it does flash too )))

An LPT port and 5 wires )))))  
Doesn’t the blue site have usbasp? I think I bought one for like 100 rubles back in the day.
