Energy Harvesting with Piezo and Wireless Communication with the nRF52832

[p1widmer]

Hallo everybody,

In or project we have an energy harvesting circuit. Because of this energy harvesting from an piezo we don`t have enough power to charge all supporting capacitors for the

nRF52832! Which of the supporting capacitors could be deleted and which can I make smaller  (about 10nF or smaller)? Do anybody have knowledge in this field of use?

thanks for your support,

kind regards

If you don't have enough power just to charge those capacitors, how are you ever going to do BLE transmissions?!?!

We`re going to write an own protocol and send just some bits. In addition we have an external LDO, which needs just an supporting capacity of 10nF.
