Figure 3- 8 Reset Control Timing
Note:
RESET_N is a sensitive signal, so it is recommended to add a debouncing capacitor close to the
module. PCB layout should be far away from the RF interference and grounded, and avoid routing on
the edge and surface of PCB (to avoid module reset caused by ESD).
3.4 USB Interface
L610 modules support USB 2.0 and are compatible with USB High-Speed (480Mbits/s) and USB
Full-Speed (12Mbits/s). Refer to “Universal Serial Bus Specification 2.0” for the timing and electrical
