H2 "Hybrid" Tibbits
The H2 form factor is used when it is unsafe or undesirable to interconnect M2 and C2 devices via a Tibbo Project PCB (or any other host board).
Examples of such cases are high-voltage and high-frequency (radio) circuits.
H2 devices can have up to eight status LEDs on the M2 side.
H2 Tibbits have no pins on their C2 "section":
Pins on the M2 section have the standard positioning, except that not all pins 1-11 might be present, because the M2 and C2 sections of hybrid devices are interconnected directly.
