STMicroelectronics SPI to Isolated SPI Dongle Based On The L99BM1T Transceiver SPI Transceiver Board STEVAL-BMS1T

The STMicroelectronics SPI to isolated SPI dongle, which allows converting SPI signals into isolated SPI signals, thus reducing the number of necessary wires from 4 to 2. The ISOSPI protocol features differential communication to ensure higher noise immunity and robustness for long-distance communications. It is based on the L99BM1T general-purpose SPI to isolated SPI bidirectional transceiver, which can transfer communication data incoming from a classical 4-wire based SPI interface to a 2-wire isolated interface.

Master and slave configuration through GPIOs or jumpers
4 configurable pins for the SPI protocol
2 configurable pins for amplitude and frequency of the converted signal
Dimensions 85mm x 30mm
