The Pyra has a range of options for data storage.
Internal eMMC Memory
Solid-state memory with 32GB capacity on the detachable CPU-Board, where the default operating system will be installed, and where you can put games, applications, and other content.
SD Card Slots
The Pyra has two full-sized SDXC card slots, externally accessible, via an MMC interface (not USB).
Hardware:
- FPS009-2960-0 - 2 x SD Card and MMC Reader - Push / Push (Reversed Type)
It also has a microSDXC card slot behind the battery, which shares with the internal eMMC memory the same interface to the SOC, but which is controlled by a software-managed switch. This theoretically allows both to be accessed near-simultaneously, albeit with a decrease in throughput.
Hardware:
- Wellco SMSN16-X0-2X00 - SIM and microSD card connector
eSATA via Adapter
eSATA support comes via an active Adapter which plugs into a USB port, but it is not a USB-to-eSATA adapter -- the additional pins that would normally be taken up with USB 3.0 signalling have been used for SATA signals. This allows far higher transfer rates than would be possible over USB. In addition, should a SOC become available in future with a second USB 3.0 interface, it could be routed through the existing connector to provide a dedicated USB 3.0 host port.
Hardware (duplicated from the USB page):
- Molex 48393-0003 - USB 3.0 Female Type A Connector
- USB 2.0 data pins connect to "HOST1-D" pins of the CPU module
- USB 3.0 data pins connect to "SATA-RX" and "SATA-TX" pins of the CPU module
Miscellaneous
Other data storage options:
- Two USB 2.0 host ports, can connect flash drives etc.
- One microUSB 3.0 otg (host-slave) port (can also be used for charging)
- One SIM card slot (behind battery, on models with WWAN hardware)
