ESPC2-12 User Manual Fig.9.1 Minimum System Note: (1) The working voltage for module is DC 3.3V; (2) The max current from IO of this module is 40mA; (3) Wi-Fi module is at download mode: IO9 is LOW level, then module reset to power; (4) Wi-Fi module is connected to RXD of the other MCU, and TXD is connected to RXD of the other MCU. 10. Recommended Layout Design ESPC2-12 module can be sold on PCB board directly. For the high RF performance for the device, please notice the placement of the module.
ESPC2-12 User Manual Solution 3: The Wi-Fi module is placed on the side of the board, and the PCB area under the antenna is empty, and copper cannot be laid. Fig.10.1 Solution 1 Fig.10.2 Solution 2 Fig.10.3 Solution 3 11. Peripheral Design Suggestion Wi-Fi module is already integrated into high-speed GPIO and Peripheral interface, which may be generated the switch noise.
ESPC2-12 User Manual can suppress overshoot when switching power supply, and can smooth signal. At the same time, it also can prevent electrostatic discharge (ESD). 12. Product Handling 12.1 Storage Conditions The products sealed in moisture barrier bags (MBB) should be stored in a non-condensing atmospheric environment of < 40 °C and 90%RH. The module is rated at the moisture sensitivity level (MSL) of 3.

ESPC2-12 User Manual FCC WARNING FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the 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.
ESPC2-12 User Manual Requirement per KDB996369 D03 2.2 List of applicable FCC rules List the FCC rules that are applicable to the modular transmitter. These are the rules that specifically establish the bands of operation, the power, spurious emissions, and operating fundamental frequencies. DO NOT list compliance to unintentional-radiator rules (Part 15 Subpart B) since that is not a condition of a module grant that is extended to a host manufacturer. See alsoSection 2.
ESPC2-12 User Manual module manufacturer reviews detailed test data or host designs prior to giving the host manufacturer approval. This Single Modular procedure is also applicable for RF exposure evaluation when it is necessary to demonstrate compliance in a specific host. The module manufacturer must state how control of the product into which the modular transmitter will be installed will be maintained such that full compliance of the product is always ensured.
ESPC2-12 User Manual Explanation: The module complies with FCC radiofrequency radiation exposure limits for uncontrolled environments. The device is installed and operated with a distance of more than 20 cm between the radiator and your body." This module follows FCC statement design, FCC ID :2AL3B-ESPC2-12 2.7Antennas A list of antennas included in the application for certification must be provided in the instructions.
ESPC2-12 User Manual The module manufacturers shall provide a list of acceptable unique connectors 2.8Label and compliance information Grantees are responsible for the continued compliance of their modules to the FCC rules. This includes advising host product manufacturers that they need to provide a physical or e-label stating “Contains FCC ID” with their finished product. See Guidelines for Labeling and User Information for RF Devices – KDB Publication 784748.
ESPC2-12 User Manual as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. Explanation: The module without unintentional-radiator digital circuity, so the module does not require an evaluation by FCC Part 15 Subpart B. The host shoule be evaluated by the FCC Subpart B.
