Arduino tinkerers, this 5-pack of Micro SD card reader modules is exactly what you need for data logging projects! These little boards let your Arduino read and write to standard Micro SD cards (including the higher capacity SDHC cards), which opens up so many possibilities for storing sensor data, configuration files, or even serving web content.
The built-in level conversion circuit is super handy - it works with both 3.3V and 5V systems, so no worrying about voltage compatibility. The standard SPI interface makes programming straightforward, and there are convenient positioning holes for secure mounting in your projects.
Each module measures about 45x28mm and includes all the necessary components. Having five means you can use them in multiple projects simultaneously or keep spares on hand. Perfect for data loggers, music players, GPS trackers, or any project where you need reliable storage. The quality is solid for the price, and they come ready to wire up to your Arduino Uno, Mega, or other compatible boards. If you're moving beyond basic blinking LEDs, these SD card modules are an essential upgrade for your toolkit!
