A microSD card reader module with built in 3.3V level shifter which allows safe interfacing to any microSD cards that support an SPI interface. This module has primarily been designed to work with our RAMPS compatible 3D printer shield (See HC3DPR0002 in our shop). The module will directly interface with the AUX-3 connector on the RAMPS shield.
Although designed for this purpose in mind, this module will work fine with any microcontoller with 5V tollerant DIO that supports a hardware or software SPI interface (see example Arduino sketch below)
Example Arduino sketch available on our support forum here.
