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).
In general, yes, the MySensors framework (library?) should support FOTA a couple different ways (read more at link). Were you aware of this, or is there some problem with your particular hardware?

I don't know yet whether you even need to change your gateway from microcontroller (uC) to Single Board Computer (SBC) or not. However if you do (or are looking for a controller, or whatever), by all means, please do yourself (and all of us) a favor and do a little more research as there are lots of better options out there for SBC nowadays, than RPi!
For me, uC have been fine for gateway although I do use some SBC for controllers, MQTT broker, and various other GNU/Linux based servers/services and they are wonderful for that. But perhaps your needs are different from mine.
Sorry for my NRF24 clone post yesterday. The ACK bit was an issue with the NRF5 platform. I had switched the memory region to handle TX/RX/ACK packages separately. Sometimes the received packages are written in the wrong region. I had seen my testing ACK bit. Now, I have changed my NRF5 code and I can't see no difference between the modules, I have. ACK and timing are exactly at the same level.
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.

I had the contact with this seller, but an international money transfer was needed and is expensive...
yeah, they also have a minimum order quantity and ship with DHL only, so you have to pay import taxes to EU
so it only makes sense if you order a big quantitiy and then try to resell it somehow
all in all a hobby that at least has some return on investment, compared to other ones i had :))
You're courageous th have gone on kickstarter, from memory seeedstudio nearly went down because of an error on a crowdfunding project and had to produce and ship (the more expensive par of it) a remlacement for the first batches...
ahh .. i didnt know this about them... and in their scale - i can undertand
it happened to me as well but in my scale it was rather a paid lesson :))))
