Hello,  
I have a project with a communication Lora, and different sensors with low consumption.  
But with an arduino pro mini + rfm95w, I don’t have enough space on the microcontroller:

```auto
text section exceeds available space in board
Le croquis utilise 33216 octets (108%) de l'espace de stockage de programmes. Le maximum est de 30720 octets.
Les variables globales utilisent 1852 octets (90%) de mémoire dynamique, ce qui laisse 196 octets pour les variables locales. Le maximum est de 2048 octets.
Croquis trop gros ; vois http://www.arduino.cc/en/Guide/Troubleshooting#size pour des conseils de réduction.
Erreur de compilation pour la carte Arduino Pro or Pro Mini

```

I can’t reduce my code. The library use most of the space.  
Do you have suggestions for a board with very low consumption and more space than an atmega328p ?
