00:00If you've ever stared at a blinking microcontroller wondering why your computer refuses to talk to
00:04it, you already know the pain and you already know the fix. A good USB to TTL serial converter.
00:11I went digging through hundreds of listings, sorted by sales, ratings, and real user feedback,
00:17and I pulled together the top 5 USB to TTL serial converter modules you can actually buy right now,
00:22and honestly, every single one of these costs less than your morning coffee.
00:26Starting off with the FT232RL FTDI module, and this is the one I keep coming back to.
00:33FTDI chips have been the gold standard for years, drivers just work on Windows, Mac,
00:37and Linux with basically zero fuss, and this one gives you a jumper to switch between 3.3 volts and
00:435 volts, so you're covered whether you're flashing an Arduino Pro Mini or an ESP module.
00:48You even get a choice between mini USB and Type-C. It's $1.68, it's sold nearly 4,800 units,
00:55and it sits at a 4.8 rating. If you want the safest, most compatible option on this list,
01:02that's this one. Next up is the CH343P, and this is the sleeper pick of the whole video.
01:10The CH343 is the newer generation chip that replaces the classic CH340, and the big upgrade
01:15is speed, we're talking up to 6 megabits per second, which is genuinely fast for serial.
01:21It's got a Type-C port, a 5V and 3.3V switch, and it's built for debugging, burning,
01:26and downloading firmware. Here's the crazy part, it's $1.08. That's the cheapest module here,
01:34and it's sitting at a perfect 5-star rating across 4,700 sales. Absolute no-brainer.
01:41Then there's the PL2303HX cable module, and this one's a little different because it's a cable,
01:47not a bare board. 4-pin DuPont connector on one end, USB on the other, and that's it,
01:53no loose jumper wires falling out of a breadboard mid-project. It supports Linux, Mac, and Windows 7,
01:59and it's perfect for hooking into a router console port, a Raspberry Pi header, or anything where you
02:04just need quick serial access. $1.35, 4.8 stars, over 4,500 sold. If you hate cable clutter,
02:13grab this one. Number 4 is the SMI CH340G module, and this is the classic workhorse of the maker world.
02:21The CH340G has been in more hobbyist projects than probably any other serial chip, drivers are
02:27everywhere, and this version has a proper 3.3 and 5V switch on board. What I really like is that
02:33it
02:33ships with the DuPont cables included, so you can plug into an STC chip or an ESP8266 the second it
02:39lands on your desk. $177, a perfect 5-star rating, and $4,400 sold. Reliable, boring in the best
02:48possible way. And rounding it out, the CH340 small board module, this is the stripped down,
02:54get it done option. Tiny footprint, breadboard friendly, and it's built specifically for
02:59downloading to STC microcontrollers and general burn and flash work. There's no extra bulk here,
03:05it's just the chip, the header, and the USB connector. At $1.41 with 4.8 stars and over
03:124,200 sold, this is the one you buy 3 of and toss in your parts drawer so you always
03:17have a spare
03:17when a project needs one. All 5 links are down in the description, so go check the current prices
03:23because these things move fast and stock changes constantly. If this helped you pick one, drop a like
