Page 15: Qwiic Connector
C connections on the Lyra 24P Development Kit are shared with the mikroBUS I C signals. The Qwiic connector and its connections to Qwiic cables and the Lyra 24P are illustrated in the figure below. https://www.ezurio.com/ Americas: +1-800-492-2320 © Copyright 2024 Ezurio Europe: +44-1628-858-940 All Rights Reserved Hong Kong: +852-2762-4823... -
Page 16: Debug Usb Micro-B Connector
Since the I/O voltage rail of the debugger remains powered in the battery-operated mode, the pins connected to the debug and VCOM interfaces maintain proper isolation and prevent leakage currents. https://www.ezurio.com/ Americas: +1-800-492-2320 © Copyright 2024 Ezurio Europe: +44-1628-858-940 All Rights Reserved Hong Kong: +852-2762-4823... -
