Micro SD / TF Card Reader Module — SPI Interface, Level Converter, 3.3V / 5V (5-Pack)
This Micro SD / TF card reader module provides SPI interface access to Micro SD and TF cards from Arduino, ESP32, Raspberry Pi, and any SPI-capable microcontroller. The onboard level converter translates between 5V MCU logic and the SD card's 3.3V interface, eliminating the need for external level shifting. Compatible with the Arduino SD library for straightforward file read/write operations. Supplied as a 5-pack.
