The HP5D is a Prototype Daughter board. It has been designed to fit onto a H-Series
SBC Main Board,
and in a
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 fully assembled, and supplied with the terminal block connector and plug as shown in the photo above.
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.
