For more accurate energy consumption measurements this device requires power monitoring calibration.
This layout is for PCB marked as “SP111_A_Wifi_Ver1.1”. It has the “3450W max” label.

To enter programming mode:
- Power the device with GPIO2 connected to GND. Red LED should turn on.
- After couple of seconds, remove the connection between GPIO2 and GND. The red LED should then turn off.
- The device is ready to be flashed.
