This motherboard is designed to replace the existing circuit board in a Bachmann Richmond 4-4-0. This board is designed to receive a WOW121 or EU621 decoder and provides an onboard KA2 and a 21-pin connector for quick decoder installation. The B-MB4 is an overall universal design, making it a great choice for brass models.
NOTE: This product does not function without a decoder. Pick up an EU621 or WOW121 decoder to use this product.
NOTE: TCS motherboards feature on-board resistors for use with LED's. This product is not intended for use with incandescent bulbs without modification or an external power supply such as the VR1.5.
All decoders are covered by a one year goof proof warranty. Please return in a small box.
You MUST register the failed decoder on our website at tcsdcc.com/warranty
Follow the instructions on the website before returning any decoders to TCS.
