The two CN9 and CN10 22-pin male headers are designed to connect with daughterboard or standard wrapping
board to STM32G0C1E-EV Evaluation board. The standard width between CN9 pin1 and CN10 pin1 is 2700 mils
(68.58 mm). The standard is implemented on the majority of evaluation boards. Each pin on CN9 and CN10 can
be used by a daughterboard after disconnecting it from the corresponding function block on STM32G0C1E-EV
Evaluation board. Refer to
