CC2640: CC2640 PCB ANTENNA FOR FLEX PCB

GAYATHRI DEVI K.V

Part Number: CC2640

Greetings from Z-crossing Solutions.

We are planning to do a project based on CC2640, which will be mounted on flex pcb of 0.2mm thickness.
All that we need to know is it possible to use MIFA for this thickness in flex PCB.
Could you please share details of MIFA to use on 0.2 mm thickness Flex PCB?

Hello Eirik,
Thank you for your concern. Let me know is it possible to power an external accelerometer using the GPIO of CC2640. As the accelerometer requires the current of 6 mA and CC2640 has driving capability of 8 mA(high side drive).
