Ordering new batteries
Inzwa recommends replacing batteries before each project to insure the longest battery life while in the field. For a device with model number Veva III (see label on back), please contact Inzwa to purchase new batteries. For all other models of the Veva III, purchase Saft LSH20 BA or Fanso ER34615M from a vendor of your choice. Please note that ER34615 or ER34615H batteries may not have enough drive current for the cellular modem.
Material Safety
- Li-SOCl2 batteries are non-rechargeable and should handled and disposed according to the material safety information provided by the manufacturer.
- Li-SOCl2 batteries have a Class 9 Hazmat shipping classification. Please follow the regulations when shipping batteries.
External Power¶
All Veva III models can be externally powered. Please click on the tab for the Veva III model you're using to learn more about connecting external power sources. Model number is shown on the back of the device.
- Locate the connector nearer to the USB symbol on the top label.
- Remove the connector cover by grabbing the textured ring on the cover with two fingers, then pulling away from the device to release the cover from the connector. Do not twist the connector.
- Connect the USB cable to the Veva III by aligning the small red dots on the connectors, then push firmly until the connector snaps in place. Contact Inzwa if you need a cable.
- Connect the device to a USB compatible power supply (minimum 2 amps).
- Once connected to an external power source, use a magnet to turn the device on, unless it's already operating using battery power.
Using USB Power Packs
-
USB power packs can be used to power the Veva III. Many USB power packs will stop supplying power to devices that draw low power. Please be certain to use power packs that are able to recharge low power devices like smart watches, earbuds or fitness trackers.
-
The Veva III E01/W01 processor operates at a faster clock rate when powered via the USB connection. As a result, the device will consume more power lowering the longevity of a power pack's single charge. We recommend using an external power solar cable when operating the Veva III E01/W01 on an external battery.
The Veva III E01/W01 has a 7 - 18 volt input available via the USB connector. To utilize this source, contact Inzwa for a special cable. This cable has a barrel connector with a terminal block adapter and will allow solar panels or power supplies to be connected to the device (see image below).
Solar panels should be at least 5 Watts and produce between 7 - 18 volts. Internal batteries should be used with a solar panel for nighttime power or a solar panel with a built-in battery.
The Veva III E01/W01 USB and external power cables attach to the USB connector on the device. Both connectors have a cover connected to a chain that's necessary for the device to maintain its IP67 capability when cables aren't connected.
Remove the cover by pulling on the textured ring (don't turn to unscrew). To attach the cover or a cable connector, align the red dots on the connectors and push to lock in place.
- Connect the device to a USB compatible power supply (minimum 1 amp) using the USB Type A to Micro B cable supplied with the device.
- Once connected to an external power source, use a magnet to turn the device on, unless it's already operating using battery power.
Using USB Power Packs
USB power packs can be used to power the Veva III. Many USB power packs will stop supplying power to devices that draw low power. Please be certain to use power packs that are able to recharge low power devices like smart watches, earbuds or fitness trackers.
- Contact Inzwa for information on compatible solar panels.
- Connect the device to a USB compatible power supply (minimum 1 amp) using the USB Type A to Micro B cable supplied with the device.
- Once connected to an external power source, the device will begin its startup process automatically, unless it's already operating using battery power.

Power Cycling the Veva III¶
Connect the Antenna
Before powering the Veva III, connect the antenna.
- Connect the supplied cellular antenna (E01 models) or WiFi antenna (W01 models) to the antenna connector closest to the symbol on the top label. The two other antenna connectors (GPS and Bluetoth) are for future use.
- Hold the included magnet within ½ inch of the magnet icon on the face of the Veva III. The power LED will illuminate red when the magnet is detected.
- To turn the Veva III on, hold the magnet to the magnet icon until the power LED turns green. Remove the magnet.
- To trigger the Veva III to shutdown, hold the magnet to the magnet icon. The power LED turns red. Remove the magnet when the power LED turns green, then wait about 10 seconds to make sure no LEDs continue to flash.
- Hold the included magnet within ½ inch of the magnet icon on the face of the Veva III. The power LED will illuminate red when the magnet is detected.
- To turn the Veva III on, hold the magnet to the magnet icon for 1 second. Within a few seconds green LEDs shou begin to flash on the device.
- To trigger the Veva III to shutdown, hold the magnet to the magnet icon for more than 3 seconds. ** Remove the magnet, then wait about 10 seconds to make sure no LEDs continue to flash.
About the magnet
Just about any magnet can be used to cycle the power on the Veva III. The device detects the north pole of the magnet.
