Overview

The TSX00004 is a MKR series expansion board designed to provide SD card storage and a prototyping area for Arduino MKR boards. It allows engineers to quickly add data logging capabilities and custom circuitry to their IoT projects using the standard MKR form factor. The shield features a microSD slot and a grid of plated through-holes for soldering components directly to the board.

Why Choose This Part

This shield provides a plug-and-play storage solution without the need for external wiring, maintaining the compact footprint of the MKR ecosystem. It includes a dedicated prototyping space which reduces the need for additional breadboards or custom PCBs during the early design phase.

Applications

Data Logging
Recording sensor telemetry to a microSD card for long-term storage in remote IoT monitoring stations.
IoT Configuration Storage
Storing network credentials, certificates, and device configuration files that need to persist across power cycles.
Custom Circuit Prototyping
Integrating unique sensors or analog circuitry alongside the SD interface using the onboard prototyping area.
