HM605 \n![AHT20_BMP280 logo](https://github.com/peff74/hanmatek_hm605/blob/main/HM605.jpg)\n\nThe HM605 is a very practical and cheap power supply manufactured by etommens and sold through Hanmatek OEM.\nIt is very easy to use and has a fairly low ripple voltage.\nAnd with a few simple steps, you can make it Modbus enabled.  \n\n\n\n## What do to\n![AHT20_BMP280 logo](https://github.com/peff74/hanmatek_hm605/blob/main/HM605_case.jpg)\n![AHT20_BMP280 logo](https://github.com/peff74/hanmatek_hm605/blob/main/HM605_port.jpg)\n\n- remove housing\n- remove display board\n- solder in a pin header\n- reassemble everything\n- check in Setup (long press on Voltage) that Modbus is active\n\n\n## How it works\n\n- use a TTL to USB with 3.3V logic level!!!\n- only GND (G) TX (T) and RX (R) are sufficient\n- TX and RX must be crossed\n- use a terminal programme of your choice\n- connect with 9600 8 N 2\n- send 01 03 00 10 00 01 85 CF as HEX\n- now you get the current voltage as a HEX value\n- more details in the ModBus-V2.2.pdf file\n\n\n\n\n## Example Output\n\n    coming soon\n\n[![Hits](https://hits.seeyoufarm.com/api/count/incr/badge.svg?url=https%3A%2F%2Fgithub.com%2Fpeff74%2FHanmatek_HM605\u0026count_bg=%2379C83D\u0026title_bg=%23555555\u0026icon=\u0026icon_color=%23E7E7E7\u0026title=hits\u0026edge_flat=false)](https://hits.seeyoufarm.com)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpeff74%2Fhanmatek_hm605","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpeff74%2Fhanmatek_hm605","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpeff74%2Fhanmatek_hm605/lists"}
