The STMicroelectronics's evaluation board is based on the ALED8102SXTTR LED driver, which is directly controlled by an STM8 MCU. It can be supplied via a USB mini connector or through J2 connected to a 12 V power supply. The board implements two automotive scenarios that you can select via the SW2 switch. The first one is an ambient light scenario based on three RGB LEDs with configurable brightness and colour. You can change colour and intensity via the SEL switch and the SW1 rotary switch, respectively. A short flashing signals the right RGB channel selection. The second scenario simulates a motorcycle rear light, two orange LED strips representing the arrow lights are placed side by side, separated by a red LED circle whose function is to simulate the position or stop lights. By slightly rotating the SW1 switch counter clockwise the left arrow light flashes, whereas a small clockwise rotation makes the right arrow flash memory.
