00:00Alright, so you're building a data logger, a music player, or maybe just want to save
00:04some sensor readings, and you need a way to get a micro SD card talking to your microcontroller.
00:09I went down the rabbit hole on this and found the absolute best deals for the top 5 SD card
00:14reader modules for microcontrollers. Seriously, some of these are so cheap you'll want to buy
00:20a handful just to have them in your parts bin. First up, we've got the classic workhorse.
00:25This micro SD card adapter module with the SPI interface is probably the one you've seen
00:31in every single Arduino tutorial. It's popular for a reason, selling nearly 5,000 units with a
00:37perfect 5-star rating. The best part is it includes a level conversion chip, so you can safely use it
00:43with both 5V and 3.3V logic without frying your card. For just a $1.58, it's the reliable,
00:51no-brainer choice that just works. Now, if you are on the absolute strictest of budgets,
00:57I found a deal that is almost unbelievable. This micro SD card SPI reader module is only $0.29.
01:04Yeah, you heard that right, less than a pack of gum. It still has the level conversion chip and
01:10works perfectly fine for basic read and write tasks. It has a 4.6-star rating, which is still
01:16really solid. If you're building a project where you need 5 or 6 of these, this is the way to
01:22go
01:22without breaking the bank. Next, we have something for the DIY enthusiasts who want a cleaner setup.
01:29This micro SD card reader module is designed for ESP32 and Arduino projects, specifically with a 3.3V
01:36interface. The key difference here is that it comes as a kit, the headers are not soldered on.
01:42This is perfect if you want to solder your own wires directly to the board for a low-profile
01:46installation in a tight enclosure. It costs $2.96 and has a perfect 5-star rating,
01:53so you know the quality is top-notch. Fourth on the list is a very tidy and compact micro SD
01:59card
01:59module. This one also features the SPI interface and the crucial level conversion for safe power supply.
02:06It's a great middle-ground option, priced at just $1.72. With over 4,400 units sold and a 5
02:14-star
02:14average, it's clear that people love its reliability and small footprint. It's the perfect upgrade from
02:21the super cheap ones if you want a bit more build quality for your permanent projects.
02:25And finally, for those who want the best of the best, we have the Adafruit Micro SD card breakout module.
02:32This is the premium choice. It's priced at $5.04, which is more than the others, but you get the
02:39legendary
02:39Adafruit quality and documentation. It supports both SPI and SDIO modes and is designed for 3.3v logic.
02:47If you want a board that is rock-solid, well-tested, and has a massive community behind it, this one
02:53is worth
02:53every penny. It has a perfect 5-star rating and is the go-to for serious makers.
02:59So there you have it, the top 5 SD card readers for your next microcontroller project.
03:05Whether you're a beginner or a pro, there's an option here for you.
03:09I've put links to all of these in the description below.
