Abstract
The optoelectronic module includes a photoreceptor circuit for picking up light from a light source by reflection on an external surface. The photoreceptor circuit and the light source circuit are mounted on a substrate, and contact pads of the circuits are electrically connected to pads of the substrate. The substrate pads are connected to conductive paths of the substrate. The flexible substrate includes a first portion on which the photoreceptor circuit and light source circuit are mounted and electrically connected, a second portion including electrical connection terminals and a connecting portion between the first portion and the second portion. This connecting portion connects some conductive paths of the first portion to the connection terminals of the second portion. The connecting portion allows the height and/or spacing of the second portion to be adjusted relative to the first portion when the module is mounted, particularly in a computer mouse.
