# Configure Hardware

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.

### Configuring Module Firmware I/O Port Information <a href="#title-3-configuring-20module-20firmware-20i-2fo-20port-20information" id="title-3-configuring-20module-20firmware-20i-2fo-20port-20information"></a>

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.
