Note: the current simulation model does not have a DOUT pin to chain multiple units together. You can chain multiple units using the "chain" attribute (see below).

Chaining#

Each dot matrix units is an 8x8 LED matrix. All the LEDs in the matrix have the same color. You can chain multiple units horizontally by setting the "chain" attribute. For example, setting "chain" to 4 will result in 8x32 matrix (four times 8x8 matrix).
