This adapter board with the dimensions 54.0mm x 17.0mm has an ESU PowerPack On Board. Although the capacitors protruding at the front and rear make for a total length of 70mm, this adapter board is ideal for converting many American H0 locomotives from Atlas or Athearn, where it replaces the original circuit board. In addition to connection pads for motor and track, there are also pads for the function outputs AUX1, AUX2, AUX3, AUX4, AUX5, AUX6, AUX7 and AUX8. The series resistors for LEDs installed there can be bridged if required. Either a LokSound 5 Nano or a LokPilot 5 Nano can be plugged into the E24 interface.
