I’m reporting a critical hardware failure that occurred during the initial setup of the LimeNET Micro 2.0, involving a LimeSDR Classic and a LimeSDR XTRX (PCIe).
System Configuration at Time of Incident:
- Host: LimeNET Micro 2.0
- Connected Devices:
- LimeSDR Classic (connected via USB through a powered USB 3.0 hub)
- LimeSDR XTRX (installed in the onboard PCIe slot)
- Power Source: Raspberry Pi USB-C PSU (not 12VDC barrel input)
Incident Overview:
Upon first power-up with both SDRs connected, a popping sound was heard from the LimeSDR Classic’s enclosure, followed by a visible puff of smoke from the LimeNET Micro 2.0. Power was immediately disconnected. Since the event, all three devices are non-functional.
Post-Incident Device Status:
- LimeNET Micro 2.0: No power LED, no boot, no serial output – completely unresponsive.
- LimeSDR Classic: No LEDs, not detected via USB, no measurable power draw on known-good systems.
- LimeSDR XTRX: Not enumerated in PCIe slot of a known-good workstation, no LEDs or activity, even with 5V barrel jack power applied.
Assessment:
This appears to be a catastrophic power-related failure originating from the LimeNET Micro 2.0 during its first use, which likely damaged both the connected LimeSDR Classic and LimeSDR XTRX. All hardware was used as documented, with no modifications.
Request:
Please advise on next steps for RMA or hardware support for all three affected devices. I can provide serial numbers, board photos, and any additional information needed to support the process.
Best regards,
Chase Valentine
