Features1.ESPC2-12 based on ESP8684 design, using ESP8684 as Wi-Fi and BLE coexistence SOC chip, very cost-effective WIFI Bluetooth 2-in-1 module.
2. The ESPC2-12 module integrates an internal memory for complete Wi-Fi protocol functionality. The embedded memory configuration also provides easy application development for the conventional electric lighting developer market.
3. The ESPC2-12 Wi-Fi and BLE Coexistence Module is a highly integrated, single-chip, low-power 802.11bgn Wireless LAN (WLAN) network controller.
4. The ESPC2-12 module supports the standard IEEE802.11 b/g/n/e/i protocols and the full TCP/IP stack. Users can use it to add Wi-Fi functionality to installed devices or it can be considered as a standalone network controller.
5. Wide range of applications, can be used in smart home, industrial IoT, transmitting market, developer market, smart power plug/smart LED lights, wireless positioning system beacons, and industrial fieldbus.

How to input program
GPI09 can be input as long as it is grounded low. After the input is finished, cancel the grounding, otherwise it will not work.
Note
1, ESP8684 RF instantaneous current can be up to 400~500mA, so the minimum power supply requirement is 500mA. XC6206, 7533 and other LD0 can not be used; 2, based on the 500mA power supply.
2, based on the 500mA power supply requirements, it is recommended that the power supply and ground alignment is not less than 30mil, the power supply line, such as over-hole, it is recommended to play 2~3, to prevent PCB production deviation; 3, for better RF performance, ESP8684 RF instantaneous current up to 400 ~ 500mA, so the minimum requirement of 500mA.
3, for better RF performance, please refer to the instructions for module placement. Way. Products such as certification requirements, it is recommended that the PCB antenna near the parallel alignment can not be, download the interface to be reserved away from the antenna pads.
4, program download before the module is recommended to wipe clean, otherwise there may be part of the phenomenon can not start;.
5、If the module can not start normally and keep restarting, it is recommended to check the power supply, including the power input, power track width, pass-through, power track, diode cascade power supply and so on,
