Power Management

5V Input with Battery Monitoring

The Grumpy Mesh Board accepts 5V input and is designed to work seamlessly with the Waveshare power board; or any other 5v power source; available as an option when you order. Unlike Heltec and RAK devices that can't recover once battery voltage drops too low (requiring an external solar controller that removes the ability to monitor battery level), the Grumpy Board features graceful power down when voltage gets low and automatically recovers when power returns. You can monitor battery level in real-time, giving you complete peace of mind over your solar deployment's.

Expansion Port

Connect Almost Anything

The Grumpy Mesh Board features a built-in expansion port, allowing you to add additional accessories like temperature sensors to monitor your enclosure or outside temperature, a wind sensor, rain sensor, and almost anything you'd like. With open documentation on how to use it, the possibilities are endless.

PLEASE NOTE:

There are no refunds on this product. If the board starts to have any kind of issues, our technical team will help troubleshoot. After troubleshooting, you will be able to return it to us for investigation, and a new board will be shipped to you.
