The HP15D is a Prototype Daughter board. It has been designed to fit onto a H-Series SBC Main Board, and in a ENC1593NBK or ENC1593NGY enclosure. This board will normally be used together with a H-Series SBC Main board, an enclosure and two enclosure panels (face plates) - see picture to the right. All terminal block contacts are numbered on the enclosure panel. Additionally space has been provided to write something next to each contact.

It is not assembled. The photo above shows the assembled board, please note that this board is not assembled! All components shown in the photo are supplied, and have to be assembled and soldered onto the board. The terminal block plug as shown in the photo above is also supplied.

There is plenty of prototype space for the user. All 40 pins (CPU port pins and power) of the 2x20 pin connector are available, and are clearly marked on the PCB. A 5 pin terminal block connector and LED is available to interface with the board. The LED is connected to the CPU port B5 via a 470 ohm resistor.
