Details

Sometimes you just want to work with CPU I/O lines directly — no logic or circuitry in between. This

Tibbit is (basically) four wires that connect its control lines to I/O lines. Complement it with terminal

block Tibbit #20 (nine terminal blocks) or #21 (four terminal blocks) and you have four CPU lines

"exposed" and ready to be used.

Note that a CPU I/O line has the voltage swing from 0-3.3V when the line is enabled (io.enabled= 1-

YES). The voltage may be close to 5V when the line is disabled (io.enabled= 0- NO). This is because

Combining this Tibbit with #21 is potentially limited in use because #00-1 doesn't have dedicated ground or power lines, and Tibbit #21 doesn't have them, either. Need ground (and power)? Consider replacing #21 with #20 (it has ground and power), or turn to using Tibbit #00-2 (it provides ground) or #00-3 (it provides ground and power).
