Part Number: RF430FRL152H

Hello everyone,

I was interessted if there is someone, who knows a little more about the engery harvesting capabilities of the RF430FRL152H, espacilally in trying to power an external component. What kind of current can you get from passive operation on the GPIO pins?

Would be thankfull for any information and experiences regarding this.

Hello Helfried,

is there a special proportion in the antennas or something that the TRF7970AEVM fullfills to get to those kind of values? Because we are struggeling to get those values with our HF-readers

Hello Nicolas,

can you please explain what you what to achieve. For tests we use the EVM boards with the PCB antenna RF430FRL152HEVM and for the reader side the TRF7970ABP Booster Pack with an EXP430 Launchpad.

Best Regards,

Helfried
