KKNGF4 (KopterKontrolNextGen) - New STM32F4 DIY Board.
Prototype board tested great and the final version is at the PCB manufacturer now. Goal of this is to provide an open source DIY board for the community to build and fly using Raceflight.
DIY board features:
- All components on top of board (except optional Baro and SWD port)
- All components are 603 size or larger for easier assembly.
- 2-Layer PCB to reduce cost
I plan on releasing all the documents including Gerbers to order PCBs, Bill of Materials, schematics and assembly guide once testing is complete.
KKNGF4 Features:
- Standard 36x36 Board (30.5x30.5 mounting)
- STM32F405RGT6: 32-Bit, 168MHz, 1MB
- 3 hardware serial ports.
- Built-in serial port inverter (UART1 RX) which allows S.BUS receivers to be used without external inverter.
- USB VCP (can be used at the same time as the serial ports).
- 4 PWM outputs (dedicated for quads).
- 5v buffering of PWM motor outputs.
- Dedicated 3.3v regulator for external devices/Spektrum (up to 500mA)
- Dedicated PPM/SerialRX input header pins.
- Dedicated SPEKTRUM adapter port.
- External SPI Connector
- Filtered inputs (UART, PPM, SerialRx)
- Dedicated I2C headers.
- MPU6000 SPI Acc/Gyro (MPU6500 possible on future version)
- Optional MS5611 Barometer on bottom of board for easy foam covering isolation.
- Blackbox Support (2 Options):
--- On-board 8mb or 16mb SPI Flash for Blackbox recording
--- On-Board MicroSD Card Support
