Connecting CR2032 to nRF6310/PCA10005

[Shane]

Hello,

I want to test my circuit using a CR2032 coin cell. Is there any way to jumper a coin cell into the supply on the nRF6310 and bypass the voltage regulator/RS232/etc? I just need to power the VCC bus on the PCA10005.

It appears that the AAA socket powers more than just the module; otherwise I could just attach my leads to the exposed AAA contacts.

I understand that there will probably not be enough current for programming the nRF51822, but assume that I have programmed the chip first via USB.

Thank you,

Shane

@Shane: If you don't use GPIO pins, you can simply hook the battery + to pin 2 of K1 (VCC_nRF); and use PCA10005 as a stand alone module.

Hung,

I have some I2C devices that I am using that I need in the circuit as well. I have them in a breadboard connected to the P8-P11 jumpers on the nRF6310, so I am really looking for a solution that allows me to interface with my breadboard while running only the PCA10005 module with the battery.

I see a jumper for nRF current measurement (P7) on the nRF6310. Will removing this jumper isolate the VCC_nRF on the PCA10005 module? Then I could plug the battery into one side of P7.

Little hesitant just to try things w/o a schematic, though.
