The interface needs a 12V DC power source and provides a stable 5V DC for the connected modules.<\/p>\n\n\n\n

For example the PCA9685 module can be connected directly to either or both of the headers. When connecting more than one module, you have to assign each module a unique address. The PCA9685 module provides 16 PWM output pins which can be used to control 16 servo’s or leds (signals). You can get the PCA9685 module<\/a> in the shop.<\/p>\n\n\n\n

With our DS-Installer<\/a> app you can flash any Arduino Nano with our DS104 sketch. Once flashed the DS-Configurator<\/a> app can connect with the interface and perform all configuration steps for all modules available. Both apps can be downloaded from our downloads<\/a> page.<\/p>\n\n\n\n
