This is a Tibbit module — part of the Tibbo Project System that allows you to build your own custom embedded device with only the components you need. Start with a Tibbo Project PCB, add Tibbits like this one, then place the built design into a Tibbo Project Box to complete your product.
Tibbit #20: Nine terminal blocks.
This Tibbit provides a terminal block interface to the outside world. It connects to any M2 Tibbit or up to two M1 Tibbits.
C2 Tibbit Modules Overview C2 Tibbits are double-width "connectors" occupying two standard C sockets on a Tibbo Project PCB (i.e. TPP2 or TPP3). They have the roughly same width and height as M2T devices: 35.2mm wide usually and 17.5mm high. Their depth varies depending on the type of connector.
C2 Tibbits have a single row of 11 pins: Pins 1-4 and 8-11 are I/O lines that connect directly to the I/O lines of two adjacent M sockets.
Pin 5 is the +5V power pin.
Pin 6 is the ground pin.
Pin 7 is the +15V power pin.
Since C2 devices have dedicated ground and power lines, they are not dependent on M Tibbits for power and ground, as C1 Tibbits are. There is no provision for connecting -15V power, though. If any C2 device needs -15V then this must be supplied by the adjacent M device.
