Package included: 1* Kakute f4 AIO V2+Atlatl stack 1* Heat sink 1* 80mm SMA--MMCX Cable 1* 150mm 4pin JST GH wire Holybro Kakute F4 AIO V2 MCU: STM32F405RGT6 32-bit processor IMU: ICM20689 (SPI) Barometer: BMP280 USB VCP Driver (all UARTs usable simultaneously; USB does not take up a UART) 5 hardware UARTS (UART1, 3, 4, 5, 6) Supports serial receivers (SBUS, iBus, Spektrum, Crossfire) only. PPM and PWM receivers are not supported. Features: -Additional UART (UART 4) added to support serial camera communication such as to RunCam Split. Please note this is NOT the same as Betaflight Camera Control feature, which controls the menu of FPV cameras like Swift, Monster, etc. -Additional UART (UART 5) added to support ESC telemetry such as from BLHeli_32 and KISS. -Through-hole solder pads instead of flat pads for more secure soldering especially for beginners. Please ask by message for more details Atlatl HV specification: Item Name: 5.8G 40CH 15/25/100/200/400/600mW FPV Transmitter Transmitting Output Power: 15mW ( Pit Mode) 25mW/ 100mW/ 200mW/ 400mW/ 600mW Switchable Audio: 6 MHz + 6.5 MHz Mono Input Voltage: 7-24V (2-6S Lipo) Dimension: 35(L)x 35(W)x 7(H)mm Mounting Hole: 30.5x30.5mm Weight: 10.8g Features: -Telemetry input allows remote control by the flight controller (where supported). Change channel, transmit power, and more from Betaflight OSD, flight controller USB port, Taranis, and more. -Variable transmit power from 25 mW to 600 mW. Use 25 mW for a race and then easily switch to 600 mW for freestyle. Please ask by message for more details
