Expand Your Project’s Memory with the Ultimate DIY Storage Solution
Take control of your embedded systems with this high-performance Micro SD Card Module. Designed specifically for 3.3V logic levels, this TF Reader is the perfect companion for Arduino, ESP32, and STM32 microcontrollers. Unlike standard modules that come with pre-soldered headers, this version offers a blank canvas for your custom PCB designs or direct soldering applications, giving you complete flexibility in how you integrate external data storage into your projects.
Key Features & Technical Highlights
- Native 3.3V Compatibility: Operates safely and efficiently with 3.3V microcontrollers, eliminating the need for level shifters in most standard setups.
- DIY-Friendly Design: Comes with headers NOT soldered, allowing you to choose between through-hole insertion for prototyping boards or direct soldering for permanent, compact installations.
- Wide Microcontroller Support: Fully compatible with popular platforms including Arduino (Uno, Mega, Nano), ESP32, ESP8266, and STM32 series.
- Standard SPI Interface: Utilizes the standard SPI protocol (MISO, MOSI, SCK, CS) for fast and reliable data transfer rates.
- Secure Card Hold: Features a sturdy TF card slot with a locking mechanism to prevent accidental ejection during operation.
Why Choose the Headerless Version?
By selecting the version without pre-soldered headers, you gain significant advantages in terms of space efficiency and design freedom. If you are designing a custom PCB, you can solder the module directly to your board, reducing the overall footprint and improving signal integrity. For breadboard users, you can simply insert standard male pin headers yourself, ensuring a perfect fit for your specific setup. This module is an essential tool for developers looking to log sensor data, store audio files, or manage configuration settings in their IoT and robotics projects.
Application Scenarios
Whether you are building a weather station that logs data over time, a music player for an ESP32, or a data logger for industrial automation, this Micro SD module provides the reliable, non-volatile storage you need. Its compact size and straightforward wiring make it an accessible addition to both hobbyist and professional engineering projects.
