Services and Prices

Edition of 22.10.2026.

Danger Drones Lab provides an IT service of access to the Danger Drones Lab software suite: Firmware for ESP32-C3 boards that control analog video, and the Site's online services (web flasher, updates, guides, support chat).

What you get

• Activation Key — a code in the "My Keys" section of your account. It appears automatically after the payment is confirmed.
• Slot — the right to activate the Firmware on one board. A Key contains as many Slots as you paid for.
• The Firmware is written to the board with the Site's web flasher (Chrome, Edge or Opera browser, USB cable).

Before you pay. The first flash of a board through the Site uses one Slot and binds it to that board. On the first start, Secure Boot and flash encryption are switched on permanently: after that the board accepts only Danger Drones Lab Firmware and cannot be re-flashed over USB; it is updated wirelessly. Board and computer requirements and the list of verified hardware are in the Technical Requirements.

Smart VTX Control (STC)

Firmware for a board on the drone that controls an analog video transmitter (VTX).

• VTX channel and power switching from the RC radio (CRSF / ELRS receiver): 6 band/channel presets, power levels, PIT mode.
• Setup from a phone over the board's own Wi-Fi network.
• VTX tables: library, Betaflight vtxtable import, custom tables; SmartAudio and Tramp protocols.
• VTX test from the menu: response, PIT, every power level and channel.
• Firmware updates over Wi-Fi from the Site.

Verified VTX models are listed in the Technical Requirements.
