Kakute H7 Mini   Description:   The Holybro Kakute H7 Mini is a Flight Controller full of features including onboard VTX ON/OFF Pit Switch with battery voltage, HD System/VTX & 4in1 ESC plugs, barometer, OSD, 6x UARTs, easy soldering layout and much more. The Kakute H7 Mini builds upon the best features of its F7 predecessor and further improves on hardware components and layout. HD ready, it has an easy plug to power HD system like Caddx Vista while supporting analog system. It features an onboard “VTX ON/OFF Pit Switch” that allows you to completely power off the video transmitter using a switch on your RC transmitter. Great if you are working on your drone, waiting for the GPS to get a fix, getting ready for a race while preventing it from overheating or interfering with others flying. It has 6x dedicated UART ports with built-in inversion for peripherals, 4in1 ESC plug, and x8 compatible with M5-M8 Signal Pads, allowing easy support for x8 Octocopter configuration. The integrated BetaFlight OSD makes it easy to display important information on your FPV display like battery voltage, flight time, warnings, RSSI, smart audio features and more. It is also ready for autonomous flight with the on-board barometer. There are LED & buzzer pad, I2C pad (SDA & SCL) for external GPS/Magnetometers. Update: Version 1.3 now has 1Gb Nand-Flash memory & BMI270 (instead of MPU6000).       Tekko32 F4 4in1 mini 45A ESC   SPEC:   F4 MCU with BLHELI32 firmware   Maximum PWM output upto 96K (default 48K)   Amperage meter scale ratio has been adjusted to 168.   PWM input, TLM supported   Voltage output (VBAT)   NO output BEC   Supports oneshot / Multishot / Dshot PWM   Supports damped light   Supports 3-6S lipo input   Ext. cap needed for 6s (1000uf 35v for 6s usage.)   Mounting holes: 20x20mm(M3)   Size:30 x 39 mm   Weight: 7.2g   Tekko32 F4 Bigfet 4in1 50A ESC   F4 MCU / PWM output up to 96K / 4~6S / BLHELI32 Tekko32 F4 BigFET are made for those that uses 20x20 mount and also need the power of big MOSFET. The F4 MCU & quality big MOSFET onboard will provide smooth control, quick response, and big power for racers and freestyle pilots.   Features:       New F4 MCU, much faster than F3 & F0     PWM output up to 96K (default 48K)     20x20 Mount design with big MOSFET     Separate drive & control circuit, this broadens the current capability of the drive circuit while reducing the electrical interference to the control circuit.       Specification:       Continuous Current: 50A x4     Burst Current: 60A x4     Supports 4-6S battery     Supports DShot 150/300/600/1200 & MultiShot/OneShot/Proshot/PWM etc.
