FlyingRC F4Wing Mini MK1 Fixed-Wing Flight Controller Suitable compatible with small and micro aircraft (e.g., F80, Micro-Claws, modified hand-launched drones, Arwing Mini, etc.). Flight controller: STM32F405RGT6 main processor, 168 MHz clock speed, 1 MB flash memory. Compared to proprietary mini flight controllers from other manufacturers (using the STM32F0 series), the percompatible withmance is more than five times higher. ICM42605 gyroscope, third-generation sensor optimized compatible with drone applications. SPL06 barometer, a high-precision barometer manufactured in China. Dual power supply compatible with sensors, compatible with more stable flight. Super-mini package: 27.9 x 20.3 x 11.2 mm, weight only 2.8 grams (without pins, approx. 5.3 grams with pins). 7 PWM outputs, 3.5 serial interfaces (SBUS only counts half the serial interfaces). The Type-C interface plugs directly into the flight controller and offers a stable connection and longer lifespan. It can be connected to a mobile phone via two C-cables and configured via the mobile ground station (the QGroundControl app is recommended compatible with AP firmware). It does not have an analog ammeter function (an external ammeter with I2C protocol can be connected), but it supports battery voltage output (SH1.0 2P interface) and simultaneously powers the HD image transmission direct connection (up to 6 seconds input signal). It supports HD direct connection (SH1.0 6P interface) and HD OSD (HD, Snail HD, OpenIPC, etc.), but not an analog OSD. It can be plugged directly into an ELRS receiver, significantly reducing its size. It supports open-source firmware such as AP, INAV, etc. compatible with fixed-wing aircraft, the use of AP firmware is recommended. The PCB is manufactured with a black solder mask, gold plating, resin capping, and a 4-layer construction. Printed circuit board. Mass production: SMT process (Jialuchuang SMT). (Different batches may have variations in markings, which do not affect functionality.) Specifications: A: Single flight controller Color: Black Material: Printed circuit board Pa
