DeepSpace Talos H7 AM32 40A AIO

DeepSpace Talos H7 AM32 40A AIO is an AIO board combining a flight controller and 40A ESCs with AM32 firmware. The board is suitable for smaller freestyle drones and Cinewhoops powered by a 3-6S LiPo battery. It can be used with both analog and digital video transmission – the board features an OSD chip for analog video as well as a connector for direct connection of the DJI O4 Pro. The flight controller runs Betaflight firmware.

The flight controller is based on an STM32H743 processor clocked at 480MHz combined with an ICM42688P gyroscope. According to the manufacturer, it handles an 8 kHz PID loop, and with bidirectional DShot the processor is only loaded to 25%, leaving a large performance reserve compared to the F405 and F722. The board features a DPS310 barometer for altitude measurement and 16MB memory for blackbox logging. There are 6 UARTs available: the receiver connects to UART4 and the GPS module to UART6. I2C pads (SDA, SCL) are provided for a compass. Two BECs provide 5V/2A for the receiver, GPS, camera and LED, and 9V/2A for stable video transmitter power. The board also has pads for an LED strip, buzzer and camera control, as well as a BOOT button and two status LEDs.

The DJI O4 Pro or O4 Wide digital video transmitter connects solder-free via a 6-pin connector on the underside of the board using the included cable. It is powered directly by the 9V BEC. An analog video transmitter and camera are soldered to the VTX, CAM and 9V/5V pads, and the video transmitter is controlled via TX1 (IRC Tramp).

The ESCs use AM32 firmware, which supports telemetry and bidirectional DShot, enabling RPM filtering in Betaflight. They handle a continuous current of 40A per channel, making them suitable with plenty of headroom for 2004 size motors and similar. They are built on a 6-layer PCB with low on-resistance MOSFETs that generate less heat. TVS diodes suppress voltage spikes when connecting the battery as well as back-EMF spikes from motors during hard braking. The board includes a current sensor.

The mounting hole spacing is 25,5x25,5mm, board dimensions are 34x35,6x9mm, and weight is 8,5g. The battery is soldered to the B+/B- pads. We also recommend soldering the included capacitor to these pads to suppress voltage spikes. An XT60 connector and two 16AWG power cables are included. The USB-C connector is located directly on the board. An external USB-C board is also available and connects via a 4-pin connector on the underside. It is useful where the board is difficult to access after assembling the drone.
