Usb Serial Converter - Usb To Serial Converter - USB Serial Adapter CH340G 5V/3.3V USB to Ttl-uart For Arduino Pro Mini (Serial Usb Converter)

like I said today we're gonna be looking at usb-to-serial adapter Zoar USB to TTL adapters whatever you want to call them really they're pretty similar so they'll do these ones here I have a switches on so they'll go from 3.3 volts to 5 volts which is useful I guess if you're going to be dealing with low powered TTL devices now you might want to use these in some scenarios with things like and I'll do we know you usually have a USB so you can connect it directly to computer however sometimes you'll just be using the bare chips so like an 80 mega a three to eight or an 80-ton 85 and you're gonna want to be able to communicate with them via serial in some fashion alternatively you might have a Raspberry Pi model a plus which doesn't have networking built in and so you might want to bring up a serial terminal by pulling off the RX and TX pins again you might want to use that with an esp826
