No Resistor Welding, Need to Weld
Remark: (Note: Default does not weld 3.3V regulator tube, only has empty position, also does not have stable to send. Regulator tube type is: HT7333)
1. This product can accommodate ESP-07, ESP-07S, ESP-12E, ESP-12S, ESP-12F, etc.
2. This product is not a soldering iron, nor is it a module, welding resistors, but resistors have been sent, soldering iron has been sent
If the VCC power supply is 5V, the 0 resistor R2 must be removed!!!!!! Weld it well on the back of the HT7333 voltage regulator chip to use normally, otherwise there is a risk of module burning
