2 x AA Battery Holder with On/Off Switch & JST PH Connector
Two-cell AA holder with genuine JST-PH connector and on/off switch. Alkaline output 2.2–3.2V, NiMH 1.8–2.7V; polarity matches Adafruit LiPoly/LiIon battery JST wiring.
Pinout
- JST PH positive output
Positive output from the 2xAA battery holder through the JST PH connector and inline switch. Adafruit states the holder connects two AA cells in series and that its polarity matches Adafruit's 2-pin JST cable and Li-Ion/Poly batteries.
Type · powerVoltage · About 3 V nominal with two alkaline AA cells; Adafruit states roughly 3.2 V when new down to 2.2 V at end of life, or 2.7 V to 1.8 V with NiMH cells. - JST PH negative output
Negative/return output from the 2xAA battery holder through the JST PH connector and inline switch. Adafruit states the connector polarity matches its standard 2-pin JST cable and Li-Ion/Poly batteries.
