IDC plug to connect actuators to the Spark 3 (set of 4)

A set of four WR-TBL Series 3587 pluggable terminal blocks.

We ship 5 of these with the Spark 3, one for each output port. If you need more to swap between actuators or lost them, you can buy this set.

Due to the ports on the Spark 4 being positioned differently, these are not suitable for the Spark 4 and the 1-Wire GPIO module.
