This MCU was hard to re-solder. You can see why by looking at the picture. I had a heck of a challenge with removing short-cuts and making sure every pin was soldered, but finally the Led blink normally and current usage is back to 10mA.
Another modification I need on some of the motor controllers are a EEPROM or FRAM to write data – I say might because I will only need that if I have a need to write things often. For now I can manage with a MCU Flash page for configuration parameters. The difference is that Flash can be written ca 100,000 times while FRAM can be written 10 trillion times. But, where should I put it ? Can you see any spare space on this board? I have to think about that one. But, for now I can start checking ADC readings – starting with DC-Rail.
