I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hi,
We are implementing a device where we need to use BLE and PWM. For generating PWM we use app_pwm library. To decide on the number of cycles of PWM pulses, we use a separate...
Hi,
Is there a way to power only the nrf52832 on the development kit(PCA10040)?
Background: We would like to test a solar power source but we don't want to power the...
Thank you very much in advance for any help.
