Development of a Flight Controller for Fixed-Wing UAVs An experienced Embedded Hardware Engineer is needed to develop a flight controller for fixed-wing UAVs. Tasks: develop the electrical schematic; design a multilayer PCB; select the component base; prepare Gerber, BOM, and Pick&Place for mass production. Main requirements: microcontroller STM32H743 or equivalent class; functionality similar to Matek H743-Wing V3 (without copying); compatibility with PX4 or ArduPilot; interfaces: CAN, UART, SPI, I2C, USB, PWM; support for connecting GPS, IMU, barometer, telemetry, and other peripherals; maximum use of components that meet NDAA requirements (without using Chinese components where possible). Mandatory when responding: describe your experience in developing Flight Controllers or other Embedded platforms; provide examples of completed projects; indicate which CAD systems you use (Altium, KiCad, etc.); specify estimated timelines and costs for completion. Preference will be given to contractors with experience in developing electronics for UAVs, robotics, or avionics.

There is a board with esp32, sim800l, mini 560pro 5v. It has two pulse inputs (coin, bill). 1. A 6-pin connector (mdb) needs to be made. 2. Integrate power into the board, it can be replaced with ti, Pololu D24V5F3 6-30V 3.3V / 1.5A, as a choice or integrate the existing module into the board. 3. Replace sim 800l with another module (the pins fit, but differ in places). Gerber files are available, there are no schematics, base jlpcb.
