  • First quick test
  • Log     from IR UART
  • Right after the assembly, a basic test confirms the modules work, though the pulse generator frequency is somewhat off. Replacing a 6.8 kΩ resistor with a 4.7 kΩ should fix this. When one module is fed with the 1 kHz signal (from the oscilloscope reference...

  • EXTRA UPDATE - DANGEROUS?

  • Log     from NOOBIX IOT
  • READ THIS:● Some of you guys on the community commented that the AC high voltage clearance is too low. YES, YOU ARE RIGHT! I usuall add copper plane to all my PCBs and that was a mistake made ina hurry. So even if you see a bad clearance in the...
