SD/MMC Card Support
The FM430 Flight Module includes built-in Secure Digital / Multimedia Card (SD/MMC) support. On-board storage capacity is limited only by the card chosen, up to 2GB. Each CubeSat Kit includes a binary (i.e. library) version of HCC-Embedded's EFFS-THIN Flash File System, a small-footprint highly scalable DOS/Windows-compatible file system supporting FAT access to SD cards.
+3.3V power to the SD/MMC card is under software control of the FM430's MSP430. This allows the FM430 to conserve power when no access to the SD/MMC card is pending. By deselecting the SD/MMC interface in software, USART0 can function as an I2C master for user I2C circuitry connected to the CubeSat Kit Bus.
Data throughput between the mass storage device and the on-board modem is maximized and latencies are minimized by associating USART0 with the mass storage device and USART1 with the modem.
