An improved and updated variant of the original Meshtastic Mini
A user on Discord pointed me to a PCB design on a chinese website (https://oshwhub.com/shenye894/meshtastic-mini), intrigqued by the down sized form factor of the obviously heavy inspired Faketec design and the almost identical used parts I ordered a bunch of them. After I received the parts I started building it right away and it worked flawless for the most part. Some issues with wrong hole diameters, wrong and confusing labeling, a missing short pad for boost charging were quickly fixed. Driving the board to its max potential there is now a 3rd mosfet for an additional rumble motor, as well 3 exposed more gpios for a navigation switch and also a notification LED, the board now pretty much offering evereyhting meshtastic has to offer. The already implemented buzzer and GPS mosfet worked perfectly fine.
##Meshtastic APP PINOUT configuration:
External Notifications: BUZZER: 8 activate "use PWM buzzer" / LED: 6 activate "Output LED active high" / Vibra motor: 38
Canned Messages(Navigation switch): EncoderA: 39 / EncoderB: 33 / Press Port: 34
The corrected and updated version is on the way to me and once I can confirm it working accordingly I will relase the files for it here.
The boards arrived yesterday and I can confirm everything working as expected!
below you can see some more shots of the PCB and first fully featured test build utilizing every single option there is available:

First Prototype build using the MiniX-Faketec board, "MiniX-Mighty" is a fully featured (All the stuff you see connected to the test build earlier) upgraded variant of the bumblebee, everything working perfectly, cant wait to publish the design once I tweaked a few more things to make it more "build friendly" ;)
