Steve Massikker's video: URB unit - one device for all model railway electronics

Assembling of the circuit by connection wires over the breadboard is a very inconvenient task. As the circuit becomes more complicated and the components added, problems are added with the correctness and reliability of connecting the wires and blocks. Therefore, I suggest you make a free URB unit that solves not only these problems but also adds new tremendous functions. You can collect a similar scheme on the breadboard, but URB is much more convenient! This board uses Arduino NANO. Therefore, the dimensions of URBs are only 60x70 mm, which makes it possible to hide it even inside model building. This solution provides excellent flexibility, maintainability, simple mass production and low cost. The board is designed to avoid incorrect connection of Bluetooth modules and Arduino NANO.
