The Rodeostat FeatherWing is sold as an unassembled kit. The kit includes the Rodeostat FeatherWing v0.3 board (PCB with all of the smt components), and a set of through-hole components. These are i) 3-pin screw terminal connector (blue), ii) 3 x male headers: 3-pin, 12-pin and 16-pin and iii) ground clip.
Before you can use the Rodoestat FeatherWing, you will need to solder the through-hole parts onto the board as shown in the images below.
i) Orient the blue 3-pin screw terminal connector so that the side with the connectors is facing out as shown below.
