Integration notes for LMTTM030XDHG30
The bridge board is an HDMI sink: the host outputs a normal HDMI signal, the board converts it to the panel’s RGB interface and drives the backlight. No panel driver is installed on the host.
480 × 480 is not a standard CEA video mode. Set the timing explicitly in the operating-system display configuration and confirm the board firmware accepts it before production.
Power the board from USB 5 V. HDMI signal and USB power are separate connections; do not power the panel through the FPC.
Use the supplier drawing for the panel outline, the 75 mm FPC and the board mounting holes. The drawing carries the tolerances; the figures on this page are nominal.

Model-specific questions
What resolution and interface does LMTTM030XDHG30 use?
480 × 480 pixels on a round IPS TFT panel. The panel side is a 40-pin RGB FPC; the host side is HDMI through the HDMI-RGB40P-V06 board.
Can I drive it from a Raspberry Pi?
Yes, from any model with an HDMI output. Set the 480 × 480 timing in the OS display configuration first; the kit does not rely on a Pi-specific driver.
Is touch included?
No. This model is supplied without a touch panel. A touch assembly would be a different model and must be confirmed separately.
What is needed for a quotation?
Specify LMTTM030XDHG30, the option (display only, display plus board, or board only), quantity, host platform and the operating environment. Price, stock and lead time are confirmed in the quotation.
