Handlet™ – With Battery

Handlet™ – With Battery

Please, see the Simplest Scenario how to get started with Handlet™

Perfect for remote projects where you want to ensure Handlet™ will keep running for a while without power supply, to prevent Handlet™ from shutting down during power outage or just to make Handlet™ portable! The portability can be handled e.g. by PiJuice HAT (which we promote here) but there are also other possibilities like for example StromPi.

With PiJuice HAT it’s possible to make the power supply also “portable” by using PiJuice Solar Panel.

No soldering or wiring is needed!

Prerequisites

Please, see the Simplest Scenario how to get started with Handlet™, everything else in this tutorial is built on top of the mentioned scenario.

Get the PiJuice HAT from any dealer of your want. The PiJuice HAT comes with a 1820mAh as standard. Perfect for remote projects where you want to ensure Handlet™ will keep running for a while without power supply, to prevent Handlet™ from shutting down during power outage or just to make Handlet™ portable. Also larger 12000mAh Lithium Ion battery is available. Please, see all the features at Pi Supply.

Some cable ties if larger 12000mAh battery is installed. Otherwise no other accessories needed.

Step 1. Remove plastic support from PiJuice HAT

Remove the plastic support pieces on the other end of the PiJuice HAT. Leave only the one supporting the battery (at the bottom of the picture), so the battery keeps steady in place. There’s usually some tape cover between the battery and the PiJuice HAT power part (at the top of the picture). Keep it still inctackt.

Step 2. Attach PiJuice HAT to Handlet™

First remove two of the screws that are holding Raspberry Pi in place. After this place the PiJuice HAT on top of Raspberry Pi. Pay attention that the GPIO pins are even. The Handlet™ Case Cover will give enough support for the Rasppberry Pi so that it will stay firmly in place with the two remaining screws.

Place the PiJuice HAT on top of Raspberry Pi and check that GPIO pins are even

Step 3. Optional, attach larger battery to PiJuice HAT

When installing the larger 12000mAh battery the standard one shipped with PiJuice HAT becomes useless. More detailed installation procedure is described at the Pi Supply. Once installed remember to setup the PiJuice HAT dip switches accordingly for the new profile.

Step 4. Boot the Handlet™

Now it’s time to remove the tape cover from PiJuice HAT and attach power plug to Raspberry Pi for the first boot. The Handlet™ will boot directly to the desktop if the SD-card was prepared with Raspberry Pi Imager as mentioned in the Simplest Scenario. Same happens if the Official Handlet™ SD-card image is being used.

Step 5. Install PiJuice HAT software

This step is not needed if the Official Handlet™ SD-card image is being used.

Please, install the software as described here. Configure the HAT, Wakeup Alarm, System Tasks, System Events and User Scripts as you wish. Notice that in this case PiJuice is powered from Raspberry Pi, the actual PiJuice power plug is not being utilized at all.

Open the PiJuice Settings and configure the PiJuice HAT as you wish

Congrats! You have now assembled successfully Handlet™ with battery (either with standard or larger battery). This is good starting point for other projects that require portability!
