Three-input HDMI switch for development boards

The LORDWORLD HDMI switcher accepts three HDMI sources and routes one to a single display with a button press. It is built for makers and engineers who need to share a monitor between a Raspberry Pi, a PC and a smartphone during prototyping. The board handles 4K at 30 Hz and 4K YCbCr 4:2:0 at 60 Hz for clear test output.

Fits into a maker bench without extra power

The switcher operates from the HDMI signal itself so no separate supply is needed on the workbench. It supports HDMI 1.4b and DVI 1.0 inputs, letting you connect mixed legacy and current devices directly. The built-in equalisation compensates for different cable lengths up to the rated 3 Gbps bandwidth.

Button control and cable flexibility included

A tactile switch on the board cycles through the three inputs instantly without software configuration. The automatic input/output adjustment lets you swap cables of varying quality while maintaining a stable link. No driver installation is required on the host devices.

Questions about this item

How many HDMI inputs can I connect before hitting the device limit?

The board provides three HDMI inputs that share one output, so you can connect up to three source devices at once.

Does the switch generate noticeable heat or fan noise when left on continuously?

The unit has no fan and draws minimal power, so it stays cool and silent during all-day operation.

Which cables or adapters must I already have to use this switch with a Raspberry Pi?

You need standard HDMI cables for each source and a compatible HDMI display; the board itself requires no extra adapters for Pi, PC or smartphone connections.
