SPI TF Memory Card Module Board, 3pcs Two Slot Reader Design, 3.3 / 5 Compatibility for Learning and Project Testing

Flexible Power Input: for 3.3V and 5V input makes the board easier to place in different prototype plans, so storage access can fit varied controller power schemes without extra interface changes Two Slot Storage Layout: This board places a full size card socket and a TF socket on the same PCB, helping embedded builders add removable storage access for logging tasks, firmware trials, and controller projects Development Ready Use: This module fits data logging, embedded control, practice, and training setups when a project needs practical card access, stable header labeling, and a compact board for repeated tests SPI Header Guidance: Marked GND, +5V, 3V3, CS1, CS2, MOSI, SCK, and MISO positions clear wiring with common microcontroller setups, helping users route card read and write functions through an organized header layout Compact Hardware Format: The PCB structure, metal card housings, and onboard parts tidy placement inside small electronics builds, giving makers storage capability while preserving a clean project layout
