Overo Series
V_BATT

SYS_EN
Powering Gumstix Overo series from batteries
Verdex Pro, Connex and Basix Series
V_BATT
| V_BATT |
| GND |
- Supply voltage: 3.6V - 5.0V (max. 6.0V)
This net powers the gumstix basix, connex and verdex pro motherboards and all related expansion boards. V_BATT is located on all modular connectors.
V_BACKUP_BATT
| V_BACKUP_BATT |
| GND |
- Supply voltage: 3.0V
This net connects to the pin 'VBACKUP' of the power management chip TPS65022.
<br>It exists to source power from an off-board backup battery. V_BACKUP_BATT is located on the 24-pin connector.
If your application needs a backup battery, connect a 3V Li-Ion cell directly to V_BACKUP_BATT and GND and remove R9 (0 Ohm resistor to ground).
Use a boost converter (ex. TPS61070) if you use a single NiMH battery
In systems where no backup battery is used, this net is connected to GROUND.<br>
On the verdex, this is done with R9 (0 Ohm resistor), which is populated by default on our website-sale boards.

Powering Gumstix Verdex Pro from batteries
three or four rechargeable NiMH AA cells in a battery holder work OK.
Lithium Ion batteries work well. for example VARTA 56491201012. <br> <br> <br> <br>
