Overo Series

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.
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.
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.
