Overview - Espressif ESP8266 Matching Manual

!
1.
ESP8266 is the most integrated System-on-a-Chip (SoC) with only 7 external components.
In order to achieve the optimum performance of the chip, customers only need to tune the
frequency offset and match the antenna impedance according to the crystal oscillator and
antenna.
The lack of frequency offset tuning and antenna impedance matching may reduce the RF
performance, resulting in AP scanning issue, unstable connection and unstable data
transmission.
