DIY Arduino Nano Electronic Load V2
Hello everyone! This is the version 2 of my elecronic DC load based on Arduino Nano, this is a simple and powerfull electronic DC load up to 70W, in this version I'm using 1.8 inch ST7735 tft display instead of 2x20 lcd display that I used in version 1, so now I'm able to display more information on the display, in this version I've also used INA219 current sensor instead of ACS712 the 5A version, now the current measurement has higher resolution, the voltage is also measured by the INA219 with high accuracy, on the older version I was using a voltage divider for voltage measurement, it does the job but is not accurate enaough. In my opinion this is a much better version othe electronic load.
