# HM605 

![AHT20_BMP280 logo](https://github.com/peff74/hanmatek_hm605/blob/main/HM605.jpg)

The HM605 is a very practical and cheap power supply manufactured by etommens and sold through Hanmatek OEM.

It is very easy to use and has a fairly low ripple voltage.

And with a few simple steps, you can make it Modbus enabled.  

## What do to

- remove housing

- remove display board

- solder in a pin header

- reassemble everything

- check in Setup (long press on Voltage) that Modbus is active

## How it works

- use a TTL to USB with 3.3V logic level!!!

- only GND (G) TX (T) and RX (R) are sufficient

- TX and RX must be crossed

- use a terminal programme of your choice

- connect with 9600 8 N 2

- send 01 03 00 10 00 01 85 CF as HEX

- now you get the current voltage as a HEX value

- more details in the ModBus-V2.2.pdf file

## Example Output

    coming soon
