Supercapacitor and ultracapacitor

[Yacire]

Hi All,

I have a question about use of super/ultra-capacitor in a circuit using a module BLE (nrf51822 inside) instead of accu Li-Pol / Li-ion ?

it is possible to use it with a BLE module ? Thanks.

I do not see any reason why it should not be possible to use a supercapacitor instead of a battery. I am not sure if it will be a good choice for most applications, but there should be some very relevant ones. For example, the Solar powered sensor beacon use a solar panel to charge capacitors that are used to power the nRF and other components, with no battery on the board. If supercapacitors was used instead one could think of an application where for example sunlight during the day would charge the cap enough that it could power the board throughout the entire night.
