Note that the PropIO V2 does support a standalone operation mode in which it can be powered by a +5V DC Jack without being connected to an ECB bus. The idea is that it would be possible to create a Propeller firmware allowing the board to act independently of a host controller – perhaps acting as a simple single board computer or terminal emulator. | Note that the PropIO V2 does support a standalone operation mode in which it can be powered by a +5V DC Jack without being connected to an ECB bus.

- **SD Card: ** A Mini-SD Card connector is provided which allows block I/O with any standard SD, SDHC, or SDXC memory card. A host would typically utilize the SD Card to provide a solid-state disk drive. | - **SD Card: ** A Mini-SD Card connector is provided which allows block I/O with any standard SD, SDHC, or SDXC memory card.

- | - **RS-232 Serial Interface: ** A 10 pin header is provided to support standard RS-232 serial connections. The header requires a pigtail to convert to a standard RS-232 connector. The serial port is a simple 3-wire interface (send, receive, ground). No flow control is supported, however the Propeller firmware does implement a small buffer. In the present firmware, the serial port is not addressable by the host controller, but can be used for in-situ programming of the Propeller EEPROM firmware | + | - **RS-232 Serial Interface: ** A 10 pin header is provided to support standard RS-232 serial connections.
