DIYables Micro SD TF Card Module Reader 3.3V SPI, 2 Pack Presoldered, for Arduino
Click to zoom
Quick Overview
The DIYables Micro SD TF Card Module is a compact 3.3V storage breakout that lets Arduino, ESP32, ESP8266, and Raspberry Pi projects read and write files on a standard micro SD (TF) memory card. Each board measures roughly 17.9mm x 17.9mm and carries a spring loaded pop up card socket, so the card clicks in securely and releases with a light push.
The module talks to your microcontroller over a standard SPI bus. All six pins are broken out to a presoldered header and clearly marked on the silkscreen, so wiring up CS, SCK, MOSI, MISO, VCC, and GND takes only a handful of jumper wires and no soldering work. Because the board runs directly at 3.3V logic, it pairs naturally with ESP32, ESP8266, Raspberry Pi, and other 3.3V boards, and it works with the common SD card libraries already bundled with the Arduino IDE and MicroPython.
Ideal for data loggers that record sensor readings over time, weather stations, GPS trackers, energy monitors, audio playback builds, configuration and firmware storage, and any project that needs far more storage than the microcontroller itself provides. Two modules are included, so you can keep one on the bench and one in a finished build.
Key Features
- Micro SD TF Card Storage — Reads and writes files on standard micro SD (TF) memory cards for logging and file storage
- 3.3V Operation — Runs directly at 3.3V logic, matching ESP32, ESP8266, and Raspberry Pi GPIO levels without extra parts
- SPI Interface — Standard 6 pin SPI connection with CS, SCK, MOSI, MISO, VCC, and GND for fast, reliable transfers
- Labeled Breakout Pins — Every pin is led out and marked on the silkscreen, so wiring is clear at a glance
- Pop Up Card Socket — Spring loaded push to eject socket holds the card firmly and releases it with a light press
- Compact Footprint — Small 17.9mm x 17.9mm board leaves room on the breadboard or inside a project enclosure
- Presoldered Header — Header pins arrive presoldered and ready to plug in with jumper wires, no soldering required
- Wide Compatibility — Works with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers with SPI
- Library Support — Compatible with the standard SD and SdFat libraries in the Arduino IDE and with MicroPython
- 2 Pack Value Set — Two modules included for parallel builds, spares, or classroom use
- Tutorial Support — Free online tutorials cover wiring and example code for Arduino, ESP32, and ESP8266
- Versatile Applications — Data logging, weather stations, GPS tracking, audio playback, and IoT storage
