The Lyra P Development Kit features a USB Micro-B connector, 20 breakout pads, a mikroBUS connector for connecting
mikroBUS add-on boards, and a Qwiic connector for connecting Qwiic Connect System hardware. The connectors are placed
on the top side of the board, and their placement and pinout are shown in the figure below. For additional information on the
connectors, see the following sub chapters.
