#193 Comparison of 10 ESP32 Battery powered Boards without display (incl. deep-sleep)

This year, many new ESP32 boards appeared on the market. Today I will review ten different boards which have a battery connection, but no display. All results are assembled in a comparison table, but maybe you watch the video for my explanations which might help you to understand the consequences of a particular choice, or at least to assess if you can trust my findings.
As usual, I found significant differences between the boards which can influence your buying decisions.

These are the contenders:

- And the Bare ESP on a PCB as a comparison for current consumption

These are the criteria:
- Does the board use a shielded module or just a chip soldered on the PCB?
- How many pins are broken out to pin headers?
- Does the board come with an antenna connector for an external antenna?
- Is the board breadboard friendly?
- How clear is the pin labeling?
- Does the board have an additional “flash” button?
- Is a battery switch available?
- Which battery connector do you need?
- Does the board crash if you disconnect USB?
- What type of voltage regulator and LiPo management chips are used?
- How much current does the board consume?
