Remote power control your IoT hardware and remote updating boot SD cards

Posted by jpluimers on 2020/07/16

Thomas Rini (of U-Boot and Yocto fame) mentioned these solutions for remote power control of IoT devices and remote updating SD cards in this slide State of the U-Boot – Thomas Rini, Konsulko Group:

Two power solutions I like myself are:

The combination of these allows for really flexible production and testing environments.

18650 Battery shield V3(RaspberryPi&Arduino) from lspoplove on Tindie

Posted by jpluimers on 2020/03/04

As you know Tesla has thousands of 18650 batteries. The 18650 battery is a strong existence. So we made this 18650 battery shield for maker.

Features:

  • Battery protection(Over charge or Over discharge)
  • Micro USB port Input
  • Type-A USB Output
  • 0.5A current charging
  • 1 switch control USB output
  • 5~8V Input Voltage
  • 3V & 1A Output
  • 5V & 2A Output
  • LED indicate(Green means full,Red means charging)
  • 3V output port x3
  • 5V output port x3

Charging can only be done at 0.5A, so using it as a sort of UPS seems not possible, but an interesting device nonetheless.

The other products referenced from the same page are interesting too and will undoubtedly bring me some new ideas for some projects.
