CC2530: Is it possible for a CR2032 to supply several CC2530 boards for several days, which are measuring voltage once a second continuously?

Hi Ryan,

We suppose several CC2530 Voltage Probe( by their own ADCs and RF sections)  modules working in a stacked style  and closely together since they share a CR2032 as the only DC supply in common.

We suppose they simultaniously measure once a second and transmit the data with their PCB antennas outside an equipment enclosed cabinet ( a  MW transmitter controller).

If a CC2530 board RF part outputs in typical 4.5 dBm level in a short interval once measurenment finished, how much will the current be drawn and how about the current consumption?

Best regards,

Jie

Hi Jie,

Here is some relevant documentation:

You can also perform your own tests using a power analyzer or multimeter with CC2530 development boards and SMARTRFTM-STUDIO.
