#### Spanningsdeler ADC <a href="#spanningsdeler-adc" id="spanningsdeler-adc"></a>

R12 en R13 zijn optioneel en afhankelijk van welke spanning je wilt kunnen meten.

| R12 | R14 | Maximale spanning op J9 |
| --- | --- | ----------------------- |
| 4k7 | 4k7 | 0 - 2 volt              |
| 8k2 | 3k3 | 0 - 3.3 volt            |
| 12k | 3k  | 0 - 5 volt              |
| 10k | 1k2 | 0 - 10 volt             |

#### Bouwen <a href="#bouwen" id="bouwen"></a>

Zoals altijd is het het eenvoudigst om eerst de laagste componenten op de printplaat te solderen en dan de steeds hogere componenten.

De laagste componenten zijn de SMD voltage regulator (U1, LM2937-3v3) en de processor (U3, ESP-12).

Beide zijn zgn. SMD componenten die eigenlijk niet bedoeld zijn om *met de hand* te solderen, maar het is toch vrij eenvoudig en goed te doen.

Begin met het aanbrengen van een druppeltje soldeer op één van de pads van de LM2937-3v3 (U1):

![](https://mrwheel.github.io/DSMRloggerWS/img/solder_SMD-a.png)

Plaats nu U1 op zijn plek en verwarm de pad plus U1 met de soldeer druppel nogmaals met de soldeerbout ..

Als het soldeer is uitgehard zit U1 op zijn plaats en kun je deze aan de overige pads solderen.

Voor U3 (ESP-12) geldt hetzelfde principe ..

![](https://mrwheel.github.io/DSMRloggerWS/img/solder_ESP12-a.png) ![](https://mrwheel.github.io/DSMRloggerWS/img/solder_ESP12-b.png)

.. alleen zijn er véél meer pads te solderen.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mrwheel-docs.gitbook.io/dsmrloggerws/hardware/hardware_v4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
