Hi,
I have a question regarding the width of the RF traces on the NRF24L01+. From the gerbers I notice the width is approximately 0.5mm and the separation to the closest...
Hi every one.
I have issue that: our board production have NRF24L01+ IC not good, so we need replace them by new IC.
But we dont have enough NRF24L01+ IC, we have NRF24L01...
