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.

Identifying a Raspberry Pi visually or by the cpuinfo

Two links that help me identify the Raspberry Pi devices from my collection (which misses quite a few, but is too extensive to get them all right in the blink of an eye):

Adafruit has some cool reference cards published as PDF files:

I like these the most:

TL;DR: Raspberry Pi models 1..3 become hotter and hotter under load; no housing gives best cooling.

Use PiServer to easily set up a network of client Raspberry Pi clients connected to a single x86-based server via Ethernet.

On my list of things to try:

PiServer is our new piece of software that makes it easy to create a network of Pis you can centrally control — ideal for your computing classroom or club!
