This battery holder connects 2 AA batteries together in series for powering all kinds of projects. We spec'd these out because the box is fairly slim, and 2 AA's add up to about 3V for many low voltage electronics projects, plus it has a nifty on-off switch.
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.
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.
| Pin | Position | Type | Function | Voltage |
|---|---|---|---|---|
| JST PH positive output | power | 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. | 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 | ground | 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. | 0 V return for the battery output. |
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. · 0 V return for the battery output.
Verify supply voltage and logic levels before powering up.
Module pins: JST PH positive output, JST PH negative output. Schematik maps them to your board in the app.
