Before you start using your Devboard, you need to prepare your Flipper Zero and Devboard for debugging. In this guide, we'll walk you through all the necessary steps and provide links to explore the Devboard's capabilities further.
Since the main purpose of the Developer board is to debug applications on Flipper Zero, you first need to enable Debug Mode. To do so, go to **Settings → System** and set **Debug** to **ON**.
Debug Mode allows you to debug your apps for Flipper Zero, as well as access debugging options in apps via the user interface and CLI. To learn more about Flipper Zero CLI, visit [Command-line interface in Flipper Docs](https://docs.flipper.net/development/cli).
The Developer Board comes with stock firmware that may not include all the latest features and bug fixes. To ensure optimal performance, please update your board's firmware using the instructions in [Firmware update on Devboard](#dev_board_fw_update).
If you skip this step, you may corrupt the data stored on the microSD card. Connecting external modules with a large capacitive load may affect the microSD card's power supply since both the microSD card and external module are powered from the same 3.3 V power source inside Flipper Zero.
If your Flipper Zero isn't in a silicone case, insert the module all the way in so there is no gap between your Flipper Zero and the Devboard. You may need to apply more force to insert it completely. After that, press and hold the **BACK** button to power on your Flipper Zero.
If your Flipper Zero is in a silicone case, insert the module all the way in so there is no gap in the middle between the silicone case and the module. After that, press and hold the **BACK** button to power on your Flipper Zero.
