From net:
The following pins supports internal-pull ups:

  1. GPIO2 (often labeled as "D2" on development boards) - Supports both internal pull-up and pull-down resistors.
  2. GPIO4 (often labeled as "D4" on development boards) - Supports both internal pull-up and pull-down resistors.
  3. GPIO5 (often labeled as "D5" on development boards) - Supports both internal pull-up and pull-down resistors.
  4. GPIO12 (often labeled as "D12" on development boards) - Supports both internal pull-up and pull-down resistors.
  5. GPIO13 (often labeled as "D13" on development boards) - Supports both internal pull-up and pull-down resistors.
  6. GPIO14 (often labeled as "D14" on development boards) - Supports both internal pull-up and pull-down resistors.
  7. GPIO15 (often labeled as "D15" on development boards) - Supports both internal pull-up and pull-down resistors.
  8. GPIO25 - Supports internal pull-up resistor.
  9. GPIO26 - Supports internal pull-up resistor.
  10. GPIO27 - Supports internal pull-up resistor.
