You can see there is a list in the PCB, that points to some blocks. Each blocks give you one/ multipal features. So if you want a feature that you want, just solder all the parts in that block. Here is the list of the blocks
| Blocks | Name | Feature | Priority |
|---|---|---|---|
| S-1 | Main Power Switch | Ability to turn on/ off the device | Must |
| S-2 | Continuous Charging | It prevents device the reboot when you disconnect the charger | Optional |
| S-3 | Boost & Charge | It boost the battery voltage to 5v | Must |
| S-4 | Esp32-s2 + Reset | Controls everything in the device | Must |
| S-5 | Vibration | Give vibration feedback | Optional |
| S-6 | Real Time Clock | Keeps the time when device is powered off | Optional |
| S-7 | MP6050/BME280 | Can use Gyro or see Pressure, Temp and Humidity | Optional |
| S-8 | Expansion Power Switch | Can turn off display, expansion and the modules in S-7 block | Optional |
| S-9 | IR Transmitter | Using IR mutantC can act as a TV, AC remote | Optional |
Here I Made 2 version that I think fits either of you if you are a Pro or a Newbie. See this comparison table to select which one you want to build. I will highly recommend building the Lite one as it requires less parts and time to build and you will miss a little of the features. And later on you can add you can also do your own custom build by selecting the features you want on top the Lite version.
| Features | Lite | Regular |

My dream is to build something like this, inspired by the Nokia Communicator
