The UxV/35 standard has six NRZ serial streams, often referred to as TTL serial. The easiest way to test these is by the addition of a loopback on the desired serial Tx/Rx pair. This board provides jumpers for each of the serial pairs that shorts the Tx to the Rx so that a transmitted signal on the Tx can be read on the Rx. Additionally, there are two I2C memories that can be read on the two I2C busses present on the UxV/35 stack A ribbon cable connection footprint is provided, that when loaded allows the full UxV/35 stack to be connected elsewhere.
