Do you want to connect a soil moisture sensor or a servo to a Troyka Slot Shield? Sure the solution is trivial, but to solve it you will need to create a 'wall' of pins. No need to have someone pay for your wall, this F/M adapter will save your time, money, nerves, and won't mess up your device.
Troyka modules differ from other form factors in size and contact connectors. It is for these modules that the Troyka Slot Shield and the WiFi Slot were created. Sometimes, though, you just want 3rd-party modules to work without a hassle.
The module does not require configuration. Install the adapter board on a free board slot and connect the required module to the top pins.
