---Tip---

1. The default firmware is set to I2C communication expansion mode.
It is important to note that to expand the number of slave devices, each additional
device must have a unique I2C address.
Slave devices cannot be used independently, the correct usage is in a setup where one
master device communicates with multiple slave devices.

2. Up to 6 devices can be connected, when connecting more than one device you need to reduce the maximum brightness of the on-board LED to 10.

3. There are some limitations on the expansion direction of the board due to the long distance wiring of the hardware. Only one device can be expanded on the left and right sides of the mainframe, and a maximum of two devices can be expanded downward (USB ports will prevent expansion). This creates a 2x3 grid layout with a total of 6 devices.

4. When running multiple boards, it is not advisable to set the brightness to maximum due to the large number of LED. (If all the LEDs are on, a lot of heat is generated, and the USB ports have limited supply current.)
