I'm not surprised you needed to use solder for that, since the TTL converter board is not designed to be attached to the camera.
The sensors in the Kit of Parts for the past couple of years (accelerometers, gear tooth sensors, etc.) have no connectors, just plated-through holes on the printed circuit board. Soldering is required to attach wires to them. Almost every potentiometer one might want to use for position feedback has terminals that wires must be soldered to.
Building the on-board backup battery charger circuit also needs soldering skills.
