Modify voltage for nRF52840

Question

Hello, 
 
 Now I am developing firmware for nRF5284 DK, and the one of the requirement is the voltage keep in 2.1V. 
 
 Is there any possible I can modify the voltage to 2.1V? Thank you.

Hi 
 The only way to supply the DK with 2.1V would be to use the External supply on header P21 and an external power supply. The USB cable will supplt 5V and convert this down to 3V for the nRF52 SoC. More details can be seen in the DK user guide . 
 Best regards, 
 Simon
