Stackable SD Card shield V3.0

Overview

SD Shield 3.0 is a break out board for standard SD and TF card. It is compatible with 5V and 3.3V Arduino mainboards, Arduino-compatible boards and Arduino mainboards that SPI is on ICSP instead on pin D11~13 such as Leonardo.

Compatibility

SD Shield can be compatible with many Arduino mainboards and Arduino-derivative boards working under 3V3 or 5V level. When it works with boards of 3V3 logic level, the level switch needs to be slide to 5V. When it works with boards of 3V3 logic level, the level switch needs to be slide to 3V3. For some of the Arduino boards, SPI is on ICSP and D11 ~ D13, while for some main boards, D11 D12 / D13 are not defined as SPI. In order to improve the compatibility, we design an SPI JUMPER to make it compatible with mainboards of the two different types. For details, please find the table below.
