Weak version of ELM327
Software recommended by maker is a little bit odd, answering in Chinese sometimes.
At least when I try it.
Work well with other soft, but features supported are limited.
Attached ELM327 identifier report.
Good enough for the price.

Useful module
I got it to test some old batteries.
Arrived without any instructions, that is ok because it is straightforward to use.
Connect battery, connect proper load resistance combination for desired discharge current, connect power supply -my phone charger is ok - set end voltage and start.
After few tests I appreciate that is accurate enough and flexible.
I test LiIons and NiCads, as well as regular batteries to appreciate brand quality.
Some day I will put it in a case with a load selection knob, but now a still use it barefoot.

From 0.8 to 3.3V give only 3.3V output
1 of 1 found this helpful If you need an output of 5 V is mandatory to feed it at least 3.3V, that is ok for LiIon cell.
My batch works from 0.8 V, but from 0.8 to 3.3 output is stabilized at 3.3V.
All tests were performed under 300mA load current using a lab DC variable source instead batteries.
It have some hysteresis, start to give 5V output only after 3.5V input, but keep it when battery is depleted to 3.3V.
Is good enough for hobby projects, for 50 cents/piece
