Due users rejoice, DimDim updated the Universal Signal Isolator Shield earlier this month.
The changes are as follows:
New SPI header. It just passes through the SPI signals, nothing more. It does not connect to anything on the board. New SPI_CS header. Useful only if / when connecting SPI peripherals. Reset button. Because you never know.. New circuitry for the POWER_RELAY header. It now uses a MOSFET and it includes a diode for the reverse current coming back from the relay’s coil. Decoupling cap for the IR receiver. Not absolutely necessary, but good to have. More decoupling for the DC_UNR input. Ground planes. Lower Arduino noise, at least in theory.
