The schematics of Pin47 CAP2 and Pin48 CAP1 is shown in Figure 8. C5 (10 nF) that connects to CAP1 should be of high precision. For the RC circuit between CAP1 and CAP2 pins, please refer to Figure 8. Removing the RC circuit may slightly affect ESP32 in Deep-sleep mode.
What does "slightly" mean? What happens if those caps and resistor are removed?
