8.13 3.5 mm stereo headphone connector
This headphone connector supports the CTIA standard which means the sequence of signals is Left, Right, GND
and Mic.
8.14 Socket 10×2 STMod+
On the B-L462E-CELL1 Discovery kit for IoT nodes, the STMod+ connector provides flexibility in a small form
factor application.
The related STM32L462REY6TR I/Os for STMod+ are listed in
Table 17 . The STMod+ connector is a 20-pin
2.00 mm pitch right-angle female connector.
