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 power the board from K1 pin 2, the current monitor (U2) will not be able to measure the current. You would need to power the board from VTG pins (pin 1,2,3,4 on P2 port) if you want to measure the current. Another option is to directly measure the current flow from CR2032 + to pin K1:2 but this will requires you to have an ampere meter (or power analyzer) instead of voltage meter (or oscilloscope).

Please be noted that, the current monitor does consume some current (~10uA), so if you want to measure very accurate low current consumption, you would need to bypass the current monitor and use option B.
