| + | There are 4 data lines which can either drive two 1-Wire signals or two serial data (Clock+Data) at 5V TTL. | ||
| + | |||
| + | If the device is configured for Analog RGB mode some of the data lines are hard-rewired to Power MOSFETs instead of to the internal 5V TTL voltage and can drive up to 6A of power. | ||

| + | The data line are connected to the SPI peripheral pins of the MCU. The MCU does output LED data using DMA+SPI. | ||
| The data output pins on the terminals are driven using real 5V TTL. There is a dedicated Linear Regulator which provides 5V, derived from the voltage the DC/DC converter does output. So even with long cables there should be no signal dropout because of a voltage drop. | The data output pins on the terminals are driven using real 5V TTL.
