Pixhawk 1 or 4 which one is better?

Hello everyone,

I want to buy a pixhawk for my drone delivery project. which flight controller do you think is more suitable for this task pixhawk 1 or 4 ?

Good day, pixhawk one is already out of date… you can choose the mRo x2.1 777 which is a good fc… customizable… good form factor board, and with the mcu stm32f777 or the control zero… very tiny fc

Thank you for your feedback Dave. I am going to make some research about it.
