Human Interface Board for Propeller P8X32A QuickStart Board US$34.99

Human Interface Board for Propeller P8X32A QuickStart Board

This board brings advanced functionality to the P8X32A QuickStart Board. The Human Interface Board stacks directly on top of the QuickStart development platform, creating a minimal footprint for both boards.

The QuickStart Board is sold separately.

The Human Interface Board has a VGA output for high-definition televisions and computer monitors, as well as a line-level baseband output for NTSC or PAL monitors. It has two PS/2 ports, each of which can connect to a mouse or a keyboard, and it has an infrared receiver that works with most television remotes. It also includes an infrared transmitter so it can emulate a television remote, or communicate with other Human Interface Boards. Its microSD card slot is useful for storing images or sounds to use in conjunction with the audio and video ports.

Except for the addition of a microSD card socket and the replacement of the microphone with an infrared transmitter and receiver, the I/O pin map matches the old Propeller Demo Board, giving full software compatibility with programs written to use the same peripherals. The female I/O socket thus also accepts the Propeller Memory Card board (no longer available).

The Human Interface Board can be powered from a 6V to 9V DC output AC adapter, from the QuickStart development platform's USB port, or from the power pins on the I/O header.

Like the QuickStart development platform, the Human Interface Board is an open-source hardware design, so all design files including layout, schematics, and firmware are available under licenses that allow free distribution and reuse. The Human Interface Board's design can be incorporated into new applications royalty free and without a non-disclosure agreement.
