258Tibbo Project System (TPS)
© Tibbo Technology Inc.
Pins 8-11 are control lines A-D. They are for interfacing to our embedded modules
or other microcontrollers. On Tibbo Project PCBs these pins are connected to the
main CPU.
Pins 2-5 are I/O lines facing the outside world. On Tibbo Project PCBs they go to
Tibbit connector sockets (i.e. connect to C1 and C2 devices).
Pins 6 and 12 are the GROUND and +5V power pins. Most Tibbit Modules consume
(take) 5V power. There are also power supply Tibbits that generate 5V power from
a variety of sources. Those output 5V through pin 12. As an example of power
Tibbits see Tibbits #10 and #23.
Pins 1 and 7 are for the additional +15V and -15V voltages. These are optional and
only needed by few Tibbits. A special power supply Tibbit #12 generates +/-15V
from the main 5V power.
