The Next18 adapter board is suitable if you want to digitize a very small locomotive without a digital interface, but do not want to freely wire the decoder. With dimensions of only 13.0 mm x 9.0 mm, the board is extremely small and also has a break-off fastening tab. For the functions AUX3 and AUX4, which are designed as logic outputs on the decoder according to the standard, power amplifiers (approx. 180mA each) are on board. A total of up to 6 outputs can be used. Already soldered connection cables with a length of approx. 20 cm for the most important contacts ensure easy handling and wiring.
