Items	Descriptions	Features
Holybro Atlatl HV 5.8G 40CH Raceband VTX	Transmitting Output Power: 15mW ( Pit Mode), 25mW/ 100mW/ 200mW/ 400mW/ 600mW Switchable Audio: 6 MHz + 6.5 MHz Mono Antenna Connector: MMCX 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	Compatible with all major FPV receivers from vendors such as Fatshark, ImmersionRC, etc. Supports the standard 40-channel set: band A, B, E, Fatshark, and Raceband. 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. Pit Mode allows you to power up safely without the risk of knocking other pilots out of the air. Mono audio input allows you to install a microphone, so you can listen to your motors while you fly, no matter how far away you fly. Standard 36mm form factor allows you to mount the Atlatl directly in your flight controller stack.
Holybro Kakute F4 AIO All in One V2	Item name: F4 AIO V2 Flight Controller 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. 128 Mbit Dataflash chip for Blackbox logging Dimensions: 35x43x7mm (includes USB in height) Mounting Holes: Standard 30.5mm square to center of holes Weight: 7g	Additional UART (UART 4) added to support serial camera communication such as to RunCam Split. 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. Barometer sensor on board allows altitude hold mode. I2C pad available for certain external sensors. Supports Betaflight and Cleanflight. Betaflight OSD. Change PIDs, adjust common configuration parameters, and change video transmitter channel and power level, all using your transmitter sticks and goggles. Soft-mounting built in. The IMU (“gyro”) chip on this board is mounted on vibration-isolating foam. New high-performance / low-noise / high sensitivity IMU. ICM20689 with 6-axis gyro and accelerometer. Can run at up to 32 kHz. 2 oz. copper PCB allows up to 120A maximum continuous current. Dedicated bootloader button for easy firmware flashing. Low-profile design fits into even very compact frames. Input voltage 7v to 42v. Power the board directly from the flight pack, up to 6S (on “B+” pad only). Automatic voltage monitoring. No need to run a separate vBat wire for voltage monitoring; the Kakute F4 AIO monitors voltage directly from the battery power lead. Filtered voltage output for clean, noise-free video. On-board regulators output 5v at up to 1.5 amps and 3.3v at up to 200 mA to power peripherals such as receiver, video transmitter, FPV camera, or LED strip. Supports BLHeli pass-through for easy ESC upgrade and configuration.
Holybro Tekko32 35A BLHeli_32 ESC	Item name: Tekko32 35A ESC Lipo input: 2-6S Size: 15*30mm Weight: 5.2g 32bit compatible ESC (Blheli_32) Dshot1200 up to 32kHz Incredibly small size Very low weight Auto timing feature On-Board RGB LED Build in current sensor Smooth response Compatible to Betaflight F3/F4 flight controller	Runs in conjunction with an ARM 32bit compatible MCU. It can run input signals with lower latency, at faster rates, smooths out the RPM band, is capable of both voltage and current monitoring and limiting, as well as offering customization of the brake on stop force. Unlike current ESCs, the Tekko32 ESC has A LOT of room to grow and wide compatibility range with future products. One of the nicest features with the Tekko32 35A ESC is the auto timing feature, which (essentially) is designed to offer the pilot the smoothest and most efficient flight experience available, which is a freestyle pilots dream come true! what can the increased MCU speed do? First of all, it can run input signals with lower latency at faster rates. Dshot up to at least Dshot1200, and at rates up to at least 32kHz is now supported. Secondly it allows packing of more functionality. - Like programmable pwm frequency, up to 48kHz, that can run motors even smoother, and also allows for moving of small but potentially disturbing humps in the throttle response. All ESCs have these bumps, with BLHeli_32 they can now be moved in the rpm range, to a place where the system has low sensitivity to them. - Like auto timing. Which is not the option to choose if you’re after max power. But if you want the most efficient running with very good robustness against desync, it is the perfect choice. - Like voltage and current limiting. Which is implemented in the code, and will be supported on some ESCs. Voltage limiting is desirable for fixed wing crafts. And current limiting adds protection against ESC failure. - Like programmable brake on stop force. Which allows control of the braking of fixed wing props. - Like improved direction change in bidirectional mode.
