FDM-S1-SFE board

For your own experiments, two partially populated boards are available. This allows to build own extensions like a pre-selector, antenna switch, transmit/receive switch, pre amplifiers and much more.

The boards are partially assembled, and come either with or without relays. On the board the I2C bus of the SDR is available for frequency control, further 7 individual switching signals can be used. The state of each of these 7 signals is shown with a LED for easier debugging. The breadboard space is available for own electronics. The board offers the required supply voltage as well.
