CWatch is a fully custom watch, designed from scratch. It is based upon an ESP32 module, with 2MB of PSRAM and 4MB of flash, along with 128 GB storage for custom maps of your area or apps.
It has a circular 1.28 inch display, GPS, Wifi, a mic (for simple voice commands) and other simple functions you can expect from a smart watch. With its 320 mAh lipo, it can run for upwards of 7 days, and automatically shuts down to prevent battery overcharge. It features an RTC that, in full power mode, is guaranteed to be with 50 μS of the real time. It features an 24/7 on Touch-Screen display, and compatability with most smart switches, letting you control your house from your fingertips!
I originally set out to make a custom smart watch because I always wanted to know how fast I was going, along with a hyper-acurate clock.
I was tired of having to contantly re-callibrate my watch, and it was especially terrible for my brother's watch. It was always >500,000 μS off of real time, normally well over 5,000,000 μS. For all the nice things about my watch, it really was a pain to have to reset it, especially if knowing the real time was impossible, lets say on a vacation. With this smart watch, as mentioned, it is guaranteed to be <50 μS off of real time, and thanks to its GPS capabilities, it will be eventually be able to automatically determine the time zone, no wifi needed.
Another thing was, I always wanted to know how fast I was going. Sometimes the train felt really fast, other times really slow, but I could never tell the actuall speed, unless I had a phone on me, something I rarely carry.
You can see, however, it was not an easy task. This board is so crammed full of features, that it requires 3 PCBs!
As for unshown wiring, I will basically just be stacking the boards togeather, and in the .epro file, you can see that all the pins are labeled. Like labelled pins will be wired togeather.
The LCD pins will be connected to the similarly labeled pins too.
The battery will connect to PGND, the battery's ground, and VBATIN, the battery's input running through a 0.02 ohm shunt resistor for power management.
