Introduction to the SPI LED hardware
Introduction and hardware description #
Hardware board contains connectors, buttons and some control diodes.
SPI LED Controller board inputs/outputs
DMX In / DMX Out #
input/output for DMX signal. SPI LED Controller contains standard RJ45 connectors where only some lines are used for Data +, Data – and Ground (GND).
| RJ-45 connector lines | usage for |
| 1 | D+ |
| 2 | D- |
| 7 | GND |
| 8 | GND |
Micro SD card slot #
Slot for standard micro SD Card. All the animations for digital LED strips or pixels can be saved on a FAT32 formatted card with size up to 32GB.
Mode/Status indicators #
three control diodes displaying the status of the device.
Frame sending – in case some picture is being sent to SPI out, this diode flashes.
DMX signal detected – diode flashes in case DMX signal is detected.
Power on – diode turns on if power is connected.
Animation switch buttons – You can store multiple animations on the SD Card. Using these two up/down buttons you can select which animation to play.
SPI Out #
Is a digital output for LED strips/LED pixels. Please, see SPI Out (SH04-5-GY) connector scheme on the picture below.
