Another long pause. The screen flickered.
: It can be powered via a Universal Micro USB/Type-C 5V port or through dedicated 3.7V lithium battery pads (VBAT/GND).
First, let’s address the elephant in the room. There is no standard industry-wide component labeled "VHM 314."

You might be tempted to rely on a forum post or a YouTube tutorial for your VHM 314 project. This is a dangerous gamble. The official datasheet is the legal and technical contract between the manufacturer and the user. Here is what you miss without the official document:

A datasheet for VHM 314 or a similar hardmetal might include information on:
Look at the physical component.

Two hours later, at precisely 23.5°C, with a precision voltage reference clamped to the chip’s casing, Elara powered on the Polaris-9. The warm-up sequence whined. The CRT flickered.
