I have been using an UNO without issue and wanted to try a Nano. Bought one off BangGood. Connected to Windows 10 pc.
One onboard LED goes solid red. And another flashes red every 2 seconds. In for maybe 50ms then off. Blinking like that.
PC makes no “USB detected” sound. So I’m not sure this is a driver issue. It has the CH340 chip. And I downloaded the driver. But I think the issue is lower than that. No USB sound when I connect.
I’m suspecting a dead board. But had anyone seen this?
