ESP-12K is a Wi-Fi module developed by Ensink Technology. The core processor ESP32-S2 of this module is a
highly integrated low-power Wi-Fi system-on-chip (SoC) designed for the Internet of Things (IoT) , Mobile devices,
wearable electronic devices, smart home and other applications. ESP32-S2 has industry-leading low-power
performance and RF performance, supports IEEE802.11b / g / n protocol, integrates Wi-Fi MAC, Wi-Fi RF and
baseband, RF switch, RF Balun, power amplifier, low noise Amplifier, etc.
2.4 Limited module procedures
not applicable; Single Modular Approval Request
2.5 Trace antenna designs
Not applicable;
2.6 RF exposure considerations
To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and
operated with minimum distance between 20cm the radiator your body: Use only the supplied antenna.
2.7 Antennas
The ESP-12K is an Wi-Fi Module beams signals and communicates with its antenna, which is
PCB
Antenna. The
PCB
Antenna gain is 3.0dBi. Antenna could not be in no-load state when module is
working. During debugging, it is suggested to add 50 ohms load to the antenna port to avoid damage
or performance degradation of the module under long-time no-load condition.
2.8 Label and compliance information
The final end product must be label in a visible area with the following
Host must Contains FCC ID: 2ATPO-ESP-12K. If the size of the end product is larger than 8x10cm, then
the following FCC part 15.19 statement has to also be available on the label: This device complies
with Part 15 of FCC rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may cause undesired operation.
2.9 Information on test modes and additional testing requirements
Data transfer module demo board can control the EUT work in RF test mode at specified test channel.
