The load cell may further include a plurality of electronic sensors including a first strain gauge pair and a second strain gauge pair disposed along the sensor holding portion. The load cell may further include an interface member directly connecting the electronic sensors for weight calculation responsive to application of a load to the unsupported end. In some cases, the interface member may include a flex circuit.
