What is it?

The sd card module accepts a micro sd card and has an onboard 3v to 5v TTL converter chip.

Why did you make it?

I needed a Micro SD-card module that could be interfaced with an AVR processor.

What makes it special?

All modules available lack the feature of disabling the MISO data when the chip selection is low.

this module can work with other SPI bus modules by controlling the cs pin.

Features

Accepts 5v and has onboard 3v3 regulator All SPI lines are buffered for easy interfacing MISO pin is gated with Chip Select so as can work with other devices Small and practical design with 7 Pin connector. Has exposed pins for chip card detection.

What is Included

Assembled board.
