General Tips¶
Your M-1 runs stock, upstream WLED. HUB75 matrix support lives in WLED itself now, so the M-1 no longer needs the MoonModules fork it used to ship with. Anything in the official WLED documentation applies to your device.
Pixel Forge runs on the device at http://<your-m1-ip>/pixelforge.htm. It converts images to GIFs, builds scrolling text with live tokens like time and temperature, and writes the result straight to the M-1's filesystem. No external converter needed.
The M-1 LED Matrix is using WLED MoonModules which is a fork of WLED that supports the Hub75 Matrix.
On a Rev6 controller you can move to stock WLED and keep your settings, which gets you Pixel Forge and 2x2 panel layouts. See Upgrade to WLED.
Segments carve the matrix into areas you can control separately, which is how you get four independent lines of text on one panel. Across multiple panels you can dedicate a segment to each physical panel, or run one effect across all of them.
The JSON API is how you drive the matrix from elsewhere, such as pushing Home Assistant sensor values onto the display as scrolling text. Scrolling text tops out at 64 characters on WLED and 32 on WLED-MM, so keep to one to three panels for text-heavy displays.
Watch your power. Each 64x64 panel can draw about 3A at 5V, and the controller's onboard rail only covers one of them. Details are on the Multiple Panels page.
