The isolated SPI module is designed for applications, where SPI signals need to be transferred over longer distances than usually. It is based on Linear’s LTC6820. The board is designed as two layer stack-up, with GND plane on the bottom layer and signal traces and components at the top layer. Signals and power are supplied over standard 100mil (2.54mm) pitch IDC header.
Dimension: 40.005 mm x 30.099 mm (1.575″ x 1.185″)
1 Mbps Isolated SPI Data Communication at 10m
500 kbps Isolated SPI Data Communication at 100m
Galvanic Isolation Barrier using standard transformer (1500V)
Requires no software changes in most SPI systems
3.5V to 15V power supply
SPI mode can be adjust via on-board jumpers
can act as Master or Slave (adjustable via jumper)
screw terminal for twisted pair cable (i.e. as in CAT5 Ethernet cable)
