The connector is a 4 Pin GH Molex Pico 1.25mm. Do not connect the ESP to the VCC pin of the DPS in any case. [This will destroy the voltage regulator of the device](https://tech.scargill.net/dps5020-diy-power-supply/#comment-60544).

## Installation

You can install this component with [ESPHome external components feature](https://esphome.io/components/external_components.html) like this:

```yaml

external_components:

  - source: github://syssi/esphome-dps@main

```

or just use the `esp32-example.yaml` as proof of concept:

```bash

# Install esphome

pip3 install esphome

# Clone this external component

git clone https://github.com/syssi/esphome-dps.git

cd esphome-dps

# Create a secrets.yaml containing some setup specific secrets

cat > secrets.yaml <
