Arduino Pro Mini + nRF24l01+ on a single PCB

Hi, I previously posted a topic on the French section of this forum, but it was mainly related to the PCB Antenna. Now I am publishing here to have a wider review of my complete design. This is a single electronic board that embeds the functionality of a Pro Mini (including the pinout) and the connectivity of the nRF24l01+. It is low power capable and might be interesting in applications like mysensors. Users could focus on the sensors and not waste time in setting up the radio. The kicad files can be download at the message #20 in this topic to avoid duplicated files:

I'll be glad to receive your comments!
