As smart homes go deep into human life, more and more IoT products are born. The WiFi infrared transponder remote control can realize the remote control of the home appliance through the mobile phone APP without replacing the home app. This scheme is mainly to realize the infrared remote control function through the mobile phone APP. MediaTek MT7682 links to the external router through the mobile phone APP with one key configuration, and the mobile phone APP transmits the remote control code to MT7682 through WiFi, and MT7682 sends it out through infrared to achieve the role of remote control of home appliances. Similarly, this solution also has the function of universal remote control, which has a learning function and supports NEC, RC5 and common remote controls on the market.

【MediaTek MT7682 Market Advantage】

1. Low power consumption, which is the most significant advantage of MT7682.

2. WiFi has good consistency and stable performance.

3. Small size, 5-mm x 5-mm x 0.9-mm 40-pin QFN with 0.4-mm lead pitch, built-in 8Mbits flash.

4. MCU (192MHz ARM® Cortex-M4® with FPU) runs fast.

【Scenario Test】

1. Connect MT7682 to the router through APP one-click network configuration, and MT7682 also supports airkiss one-click network configuration.

2. Add the remote control through the APP, and there are also three options for adding the remote control

1) Search for the model number on the back of the remote control via the cloud

2) Find the home appliance brand and match the remote control directly through the cloud

3) Duplicate the remote control

    3. After the remote control is added, the mobile APP sends the remote control code to MT7682 through WiFi, and MT7682 sends the remote control code through infrared

►Core technical advantages

1. MT7682 does not need external flash, which saves costs.

2. Infrared forwarding can be achieved with I/O simulation, no need to plug in the infrared chip, and the price is more advantageous.

3. The external crystal is 40M or 26M, which is convenient for customers to choose according to their own needs.

4. MT7682 chip package: 5-mm x 5-mm x 0.9-mm 40-pin QFN with 0.4-mm lead pitch, PCB can be very small.

5. Compared with MT7687, MT7682 has lower power consumption and more power saving, and the deep sleep mode can achieve tens of uA.

6. MT7682 runs FreeRTOS, supports one-click network configuration, supports airkiss network configuration, quickly links routers, connects to cloud services, and obtains rich resources.

7. MT7682 supports OTA upgrade, which is convenient for subsequent software upgrades.
