@m5stack said in The range of values from an ANGLE between directly connected to PORT B and connected to PORT A via PbHUB is different: ESP32 and mega328 has different ADC resolution Thank you very much for your reply. Yes, the ADC module on mega328 has a 10-bit resolution, whereas ESP32 has a 12-bit resolution. If this issue is just a resolution issue, the result should be 0 - 1023 instead of 15 - 745 or 0 - 715. If nobody can reproduce this issue, the PbHUB may be broken...
