About the Micro sd spi breakout module

Micro sd spi breakout module is an open source PCB design by Harshavar8jdm, published on GitHub. It is a 2-layer board measuring 28 × 22 mm, with 6 components from 5 distinct parts.

Other key parts include the TF-SMD_TF-PUSH. By type, the board carries 2 capacitors, 2 resistors, 1 IC and 1 connector.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

A compact, high-performance, 2-layer MicroSD Card Breakout Board designed in KiCad for embedded microcontrollers using the SPI (Serial Peripheral Interface) bus.

A compact, high-performance, 2-layer MicroSD Card Breakout Board designed in KiCad for embedded microcontrollers using the SPI (Serial Peripheral Interface) bus.

Designed specifically for 3.3V native logic ecosystems (STM32, ESP32, RP2040, SAMD, Nordic, etc.), this module provides clean power decoupling, signal pull-ups, and a low-EMI ground plane layout.

Native 3.3V Operation: Designed without slow active/passive level shifters, maximizing SPI bus speeds (up to 25 MHz) with zero signal propagation delay. Transient Power Decoupling: Dedicated 10 uF bulk ceramic cap (C1) and 100 nF…
