NRF24L01 differences

In terms of range of transmission does NRF24L01 with SMA antenna improve range than NRF24L01 without SMA antenna?

It depends if you want to use an antenna with some gain or not

Awesome project, I wish I made something like this. (I actually wanted to make something like this when I was in school) Very clean and nice presentation and realization, with a lot of attention to details. All is very realistic, I can imagine that it took quite some time making it. Thanks for sharing the details!

I also have project for mini. The project have pads for battery, battery protection IC, LIPO charger USB for charging... battery voltage measurements.... But the project is not released yet, because high temperature during charging.

@Dirk_H There isn't any limit. But keep the number of hops low if possible.

@schif Hello, Thanx for you comment. Yes you can use it but use a ceramic capacitor

The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle. In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V. Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work. Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).
