I-jet comes with a 20-pin MIPI connector—0.05 in × 0.05 (1.27 mm x 1.27 mm) pitch—
on the front panel. It includes two cables:
A 6-inch cable with 20-pin MIPI connectors on both ends for the Cortex-M targets
●
with 20-pin MIPI headers. Pin 7 on each end is keyed with a white plug.
A 6-inch cable with a 20-pin MIPI connector on one side (to connect to I-jet), and a
●
10-pin MIPI connector on the other side for connection to Cortex-M targets with
10-pin headers. Pin 7 on the 20-pin end is keyed with a white plug. A red stripe on
the cable indicates pin 1 (VTref).
