The RAK Hotspot Miner V2 includes two (2) small LEDs for status:
🔴 Red LED: Solid red is good; it means Pi is getting power. In normal operation, only solid red should be seen. Flashing red means there is some issue with the power supply — reconnect power and check again.
🟢 Green LED: At power-up, Green LED will blink in a random pattern, but after about 5 seconds, it should stop. If Green is blinking repeatedly for a long time, it means there is some problem - usually, this will be the SD card, but maybe a power issue too.
In the case of a constant blinking Green, refer to the following recommendations:
- Unplug USB-C power.
- Extract microSD card, check and re-insert it making sure it is well seated. The card could have moved in shipping, or the user may have inserted it incorrectly, which is upside down after backup.
- Reconnect USB-C power making sure it is plugged in all the way.
