Is there any alternative firmware for RK6006 ?
The stock firmware has several issues and manufacturer says it should be that way:
1. You can not adust tens of volts.
2. In current setting mode,if you're in 0-9mA range, when you press the encoder, instead of going into 10-99mA range, it goes into A range, so if you have some weak load connected, it will burn instantly!
3. Output voltage and current has notable fluctuations - say I set output voltage to 4V, the display reading will jump from 3.99 to 4.02 each second, and actual output will float from 4V to 4.12V!
