Common elementsAll Yocto-modules share a number of common functionalities.USB connectorYoctopuce modules all come with a micro-B USB socket. The corresponding cables are not the mostcommon, but the sockets are the smallest available.Warning: the USB connector is simply soldered in surface and can be pulled out if the USB plug actsas a lever. In this case, if the tracks stayed in position, the connector can be soldered back with agood iron and using flux to avoid bridges. Alternatively, you can solder a USB cable directly in the1.27mm-spaced holes near the connector.Yocto-buttonThe Yocto-button has two functionalities. First, it can activate the Yocto-beacon mode (see belowunder Yocto-led). Second, if you plug in a Yocto-module while keeping this button pressed, you canthen reprogram its firmware with a new version. Note that there is a simpler UI-based method toupdate the firmware, but this one works even in case of severely damaged firmware.www.yoctopuce.com 5
