I've been working with the nRF52840 WLCSP package for a month or two now, and in many ways it's a great compact chip. However, as my projects require more and more pins, I...
Hi guys, Im now developing my custom board with nRF52832 based on the reference schematic below. And using Keil uvision for a programming my board.
The final objective of...
Hi
I have two custom build boards based on nRF9160-SICA. Both boards also have a nrf52840 running application code. The nr91's are running identical firmware (slightly modified...
Dear.
Now Im testing the nRF24L01 to develop a module.
Using this, I want to know the receive power.
nRF24L01 has a registef to use similar function. Register...
Hi,
I'm trying to write firmware for the nrf52840 that reads from a sensor and then sends data to a PC over BLE. Ultimately, I need the BLE link to achieve ~ 1.1 Mbps throughput...
