This is a pair of custom Grove adapter boards from EnviroDIY, handy for connecting sensors or other devices to Grove terminals. (Note: Grove cables are not included.) One board is the Grove-to-3.5mm Stereo Jack adapter. The other board is the Multipurpose 6-pin Screw Terminal adapter. Solder jumpers on the back of the Screw Terminal adapter allow for configuration in 3 different ways. Mode 1: Default setting is for the two screw terminal signal pins (S1 and S2) to connect to the Grove jack pins (D1 and D2) in standard fashion, meaning S1 is connected to D1, and S2 is connected to D2. Mode 2: configure screw terminals S1 and S2 to both connect to the same Grove pin (D2) by adjusting the middle solder jumper. Mode 3: add resistors to the marked locations to create a resistor-divider for creating lower analog voltages. Set the solder jumpers to Res-Div to enable Mode 3.
