SpeedyBee F405 Mini BLS 35A 20×20 Stack

Features:

• SpeedyBee F405 Mini Kit with 35A BLS 4-in-1 ESC is the top-of-the-line SpeedyBee solution. It features a 35A 4-in-1 BLHeli_S electronic speed controller (ESC) and an F405 flight controller that supports the SpeedyBee phone app, allowing for convenient configuration of the drone via Bluetooth;
• SpeedyBee 50A 4-in-1 ESC supports up to 35A DC output. The ESC works with BLHeli_S firmware and comes with a 470uF low ESR capacitor;
• The flight controller supports DJI Air Unit systems via an integrated 9V 2A BEC. It has 6 UART ports for connecting accessories such as LED lights or GPS modules. It also has an integrated 8Mbit memory (blackbox) for recording flight data and an innovative 4-LED light system on the side plate that acts as a battery level indicator, showing the remaining battery capacity in percent.

Specification:

FC:

• Blackbox (internal memory): 8MB flash;
• BetaFlight camera control: Yes (CC contact on the front side);
• Current sensor input: Supported. When used with SpeedyBee BLS 35A V2 ESC – set Scale=250, Offset=-500;
• Power (input): 3-6S LiPo. Power via G and V wires from 8-pin connector or G, V solder points on bottom;
• 5V output: 4 groups: 3 contacts +5V and 1 BZ+ (for signal). Maximum load – 2A;
• 9V output: 1 +9V contact on the front. Maximum load – 3A;
• 3.3V output: Supported. Contact “3V3” on the front top. Up to 500 mA;
• 4.5V output: Supported. For receiver and GPS even when FC is powered via USB. Up to 1A;
• ESC signal: M1–M4 wires or solder points at the bottom;
• UART:
UART1 (OSD);
UART2;
UART3;
UART4 (Bluetooth);
UART5 (for ESC telemetry);
UART6;
• ESC telemetry: UART R5 (UART5);
• Betaflight LED: Supported. LED, 5V and GND pins on the bottom front;
• Signal buzzer: Use BZ+ and BZ- contacts (5V);
• BOOT button: Supported. Holding down while turning on the FC will enter DFU mode;
