Compute Module DSI Adapter 22PIN to 15PIN
This adapter bridges a 22PIN DSI interface on a Compute Module IO Board to a 15PIN DSI display. It is designed for developers and hobbyists integrating official or Waveshare IO boards with compatible Waveshare DSI LCD panels. The part enables direct connection without custom cabling or pin remapping.
Signal continuity under sustained load
The adapter maintains a passive electrical path between the 22PIN host header and the 15PIN display connector. No active components are present, so signal integrity depends on the host board and panel specifications. Continuous operation does not introduce additional latency, jitter or protocol conversion beyond the native DSI link.
Thermals noise and power draw
As a passive flex circuit, the adapter generates no measurable heat and draws no power of its own. It adds no audible noise to the system. Thermal and acoustic characteristics are determined entirely by the Compute Module, the IO board and the attached display panel.

Questions about this item
Does the 22-pin to 15-pin DSI adapter draw extra power or generate heat when the display runs all day?
The adapter is a passive flex cable converter with no active components, so it adds no measurable power draw or heat beyond the display itself.
Which host board must I already own to plug this 22-pin to 15-pin adapter into a Compute Module?
You need an official Compute Module 4 IO Board or a Waveshare Compute Module IO Board Plus that provides the 22-pin DSI header.
Will this 22-pin to 15-pin adapter let me keep using my older 4.3-inch Waveshare DSI LCD with a newer Compute Module 4 IO Board?
Yes, the adapter bridges the 22-pin IO board header to the 15-pin connector used by 4.3-inch and 5-inch Waveshare DSI LCDs.
