Hello sir, I have completed PCB design of custom nRF52832 board. Can i use following component instead of recommended part No in reference design. I have also mentioned mft part no that will be use. Because this recommended part number is not available…

We are currently designing a prototype board for our product using the nRF52832. We need to calculate the transmission line with on a 4 layer PCB. The stack-up looks like this: Copper 1 35 um - Signal (with surrounding GND) Dielectric 1-2 0.175…

Hello, I am going to us the meander antenna from the nrf51 usb dongle. Are there any drafts with correct dimensions? And second what should be the minimum distance between the antenna and the ground plane? In your reference design of the usb dongle…

Hi, I am trying to develop a PCB for the NRF52 that will use bluetooth capability. However, I was wondering if there were smaller antenna's that could be used rather than the one on the development kit since it will be too big. Also, I'm not sure I…

Up to this, we've been prototyping with MDBT40 module in our prototypes. We want to move to a completely custom PCB using the nRF51822 SoC for a number of reasons (space and design flexibility being of most concern). I've already designed and populated…

Hi, I'm designing an antenna for the NRF52 but with some different conditions, the antenna will be under a silicone superstrate and this will change the impedance of the antenna extracted from your designs... What is the best way to deal with it? …
