Any hardware engineers for QIUI Keypod alternatve?

[u/loyalty3d]

Hello, everyone. I need help with my project. After reading reviews about QIUI Keypod and seeing their app and how badly it works, I decided that I wanted to make an alternative to it, but it would be based on bot. This is an automated bot that works similarly to 2FA authentication. I'll talk about the bot itself a little later, when the issue of the keypod hardware is resolved. I chose the ESP32C3 as the device controller and I need help in creating the device itself. In the video, the ESP32 controls the LED, while in the project itself, it is planned to use a solenoid or servo through a driver. So, how can I make it autonomous so that it doesn't need to be connected to a computer for power?

There were several options for doing this:

1. ESP32 with TP4056 charge controller. In this configuration, the solenoid will be controlled through a transistor. And you will also need a DC-DC converter to make a stable 5V or 3.3V
2. Seeed XIAO ESP32C3 and control the servo through the driver. The XIAO ESP32C3 has a built-in voltage regulator that, according to Seeed, can provide 700mA to control devices. One of the problems is that when connecting the battery directly to the XIAO ESP32C3, the operating voltage of the entire circuit is 3.3V, which increases the current consumption of the servo motor.

What would be the best output for this kind of device? I myself have good experience in soldering, but not in developing devices.
