Powering Gumstix Overo series from batteries
Verdex Pro, Connex and Basix Series
- 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.
- Supply voltage: 3.0V
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.
