☞
The J2 Micro SD card socket shares the Arduino interface D10 to D13 pins, which are used as an
SPI bus to the HostMCU SPI4 peripheral. The D10 pin (NSS) is used as an SD card SPI slave select
signal. When the SPI bus on the Arduino interface is utilized by other SPI slaves on daughter
boards, free Arduino digital IO lines should be utilized for slave select signals.
⚠
As the SD card interface and its supply voltage are designed to work with 3.3 VDC, the SD card
socket shall not be used when the Arduino interface IOREF voltage level is set to higher than
3.3 VDC. Such usage could cause a permanent damage and/or a failure to an SD card inserted in
the J2 socket and the C030-R412M’s Arduino™ interface level translators. (See R152 and R153
links in
Table 4 ).
