[SOLD OUT] DIY Safe Shutdown v1.0 (for PowerBoost)

Post by Camble » Sat Mar 04, 2017 7:47 am

SOLD OUT

DIY Safe Shutdown v1.0 for Adafruit Powerboost.

This is the through-hole self-assembly version of Safe Shutdown v1.2 for PowerBoost

All required components are supplied, you just have to solder them onto the board.

Summary:
  • Works with software to issue a shutdown command to the Pi.
  • Keeps system powered until Pi shuts down.
  • Works with Adafruit PowerBoost 500c/1000c.
  • Works with the PowerBoost LBO pin to alert you of a low battery.
  • Through-hole components included.
  • DPDT switch included.
  • Octagonal PowerBoost Headers (BAT/EN/GND/LBO).
  • Circular Raspberry Pi Headers (3.3v/Shut-off/Keep-on/Low Battery).

Supplied:
  • DIY Safe Shutdown PCB v1.0.
  • Resistors.
  • Diode.
  • Transistors.
  • DPDT Switch.
Required: Wiring guide:
  • Octagonal BAT connects to the Bat or Vs pin of the PowerBoost.
  • Octagonal EN connects to the EN pin of the PowerBoost.
  • Octagonal GND connects to the GND pin of the PowerBoost.
  • Octagonal LBO connects to the LBO pin of the PowerBoost.
  • Circular 3.3v is the 3.3v pin (physical pin 1 or 17)
  • Circular On is the keep-alive pin, usually BCM/GPIO22 (physical pin 15)
  • Circular Off is the shutdown pin, usually BCM/GPIO27 (physical pin 13)
  • Circular Low is the low battery pin, usually BCM/GPIO17 (physical pin 11)

Please take care when handling and soldering these boards. They include static-sensitive components and have a low thermal mass. Damaged boards with burnt traces or pads cannot not be replaced.

Additional things to note:
  • This version will not work with an original DMG-01 power switch.
  • You may need a tiny blob of hot glue to prevent the PCB from rotating around the screw hole.
  • It is a good idea to test the resistor values with a multimeter before assembly.
Software:
Please remember to install the Power Monitor script, otherwise the Pi will not shut down.
Also add the following line to /boot/config.txt, or the PowerBoost will not stay on while the Pi shuts down.

Code: Select all

dtoverlay=gpio-poweroff,gpiopin=22,active_low="y"
Safe Power Monitor
I am currently working on a new power monitor script. This script makes the changes to your /boot/config.txt automatically if you haven't already done so. It is also much easier to tweak settings, and logs events to a file to help with troubleshooting.
If anyone would like to test it out, here it is.

I'd be quite interested in this :) Is it easy to build and is there a wiring diagram I could use?

@scbailey94 It's a very easy kit to build. The only thing that may trip people up is getting the transistors mixed up, but everything is marked and only goes in one place.

Wiring it up is the same as the fully assembled version. Again, I've kept things as simple as possible.

Ask and ye shall receive...

Assembly took about 5 minutes. Do the resistors first and you should be golden.
