# SoC Development Overview
### Overview
System on chip (SoC) solutions include development-free and custom firmware solutions that Tuya provides for electrical engineering and lighting products based on its extensive experience in product intelligence.
SoC development-free solution: Tuya provides many mature development-free solutions for electrical engineering and lighting products based on common functions and types of the products. After you select a development-free solution and configure product information online, Tuya will send the network connection module to you. The plug-and-play module immediately enables the settings you specify online after you connect it to your product without development.
SoC custom firmware solution: If the development-free solution cannot meet your functional requirements, select the SoC custom firmware solution. After you submit your requirements on the **Hardware Debug** page, a dedicated Tuya development team will develop the firmware and send the module with a customized panel and cloud functions to you.
SoC solutions help you quickly and efficiently make your products intelligent and mass-produce the products at low cost.
SoC solutions apply to switches, sockets, and bulbs and security\&sensor product. If you have higher development and configuration requirements for the preceding products, select the MCU development mode.
### Development Process Using a SoC Development-free Solution
#### Product Creation
**Logging In to the Tuya Smart Platform**
Log in to the Tuya Smart platform at with your Tuya account. If you do not have a Tuya account, register one.
#### Creating a Product
On the **Product** page, click **Create** in the **Easy Access to Get Your Smart Product** area.Select a product type. To create a switch or socket, click **Electrical**. To create a bulb, click **Smart Lighting**.Based on the network configuration mode and basic specifications of your product to be created, click a product image under **Plug and Play Solution**.
**Configuring Basic Product Information**
(Mandatory) Specify the product name. The product name is in *Brand* + *Product* + *Module model* format.
(Optional) Specify the product model (SN) to distinguish your product.
Confirm the communication mode. By default, the communication mode is the same as that in the previous development-free solution.
#### Configuring the Product Online
**Function Definition**
1. **Product configuration progress bar:** A product configuration progress bar is displayed on the top of the page. Configure the product information step by step.
2. **Submit your question**: Click **Submit your question** and report your development questions.
3. **Product information:**
Thumbnail: indicates the type of the product that you have created.
PID: the unique identifier of the product, which contains information about the product configuration, App, and module. Keep the product PID secure.
**Edit Product Information**: allows you to edit the product name, product model, and remarks. After modifying any information, click **Save** to save the modification.
4. **Product functions:** Click **View function details** to view functions of the product that you have created. The Tuya Smart team has defined functional solutions for smart switches, sockets, and bulbs. If the solutions cannot meet your requirements, create a custom product that does not use a SoC solution.
Confirm the product information and functions, and click **Next**.

**Hardware Debug**
If you have hardware development capabilities, select a module and configure I/O port information based on the reference circuit diagram. The module firmware will be generated automatically. After you purchase the module, Tuya will burn the firmware on the module and send the module to you for testing.
**Selecting a Module**
Click **Module details** to view detailed information about the selected module or click **Change module** to select another module. You are advised to select a recommended module that supports most product functions and can meet your product requirements.
**Checking the Reference Circuit Diagram**
The **Circuit reference diagram** area displays a diagram of the circuit between the module you select and the product.
**Configuring Module Firmware I/O Port Information**
Configure the I/O port information by referring to the Corresponding figure of IO id and module IO name figure. Check the firmware configuration information, modify it as needed, and save the modification. The module will be programmed based on the settings that you specify on this page. After the module is delivered, the settings cannot be modified. If you modify the settings after the module is delivered, any online upgrades will not apply to the product because the settings will be inconsistent. The I/O port settings for power statistics equipment, sockets, panel switches, and bulbs are different. Enter the I/O port information based on the product type.
**Purchasing the Module**
Purchase the module online for product debugging. The module contains the preceding product configuration information and can be used for product debugging after you purchase it.
**Advanced Features**
After configuring the basic product functions, click **Advanced Features** and configure the following advanced product features based on your requirements: multilingual management, firmware updates, network configuration guide, scenario association, and quick toggles.
**Multilingual**
To manage the App languages, click **Settings** next to **Multilingual**.
1. Change the language. Select a language to display the text content on the App control panel.
2. Change the product name. After you change the product name on the Tuya Smart platform, the product name will be changed in the App accordingly.
3. Change panel fields. After you change the product name on the Tuya Smart platform, the product name will be changed in the App accordingly. For example, you can change **Switch**, **Timer**, and **Countdown**.
**Firmware Updates Center**
The **Firmware Updates Center** settings do not apply to SoC solutions or the MCU solution.
**Network Connections Guides**
The custom network configuration guide settings are available only to OEM App owners. If you use the Tuya Smart/Smart Life App or if you do not select the custom category for your OEM App, the Tuya general guide will apply to your product. After you complete the settings, synchronize the confirmed network configuration information to the product user manual.
**Scenario connection settings**
**Scenario connection settings** allows you to select data points (DPs) that trigger smart scenarios and task settings. Selected DPs will be displayed in the Tuya Smart App for you to configure.
**Quick toggle settings**
On **Quick toggle settings**, select an option for your product. A switch button will be displayed for the product in the Tuya Smart App. In addition, you can add the product to the widget area on the home screen for easy control.
After you change the product name on the Tuya Smart platform, the product name will be changed in the App accordingly.
