Add new target ORBITF435

[orbittechnologyx]

Hello,
This target is already supported in official Betaflight firmware (Betaflight Wiki) . Also I want to add in official Inav firmware. Could you please review the configuration?

Here is the specs:

• MCU: AT32F435
• IMU: ICM42688P
• OSD: AT7456
• Baro: DPS368 (new version of DPS310)
• Blackbox: 16MB Flash and SD Card
• Power input: 2S - 6S LiPo (note: output will be lower than 10V when using 2S).
• Power output: 3.3V/500mA, 4.5V-5V/2.5A, 10V/3A
• RSSI input: RSSI input solder pad
• I2C: Used for external magnetometer (GPS module), Barometer module
• ESC: 8 pwm pins for motors
• USB Connector: USB Type-C
• UARTs: 6x
• SWD: Yes
• Analog RSSI Input: Yes
• LED Strip Output: Yes
• Buzzer Output: Yes
• SPI: No
• Current Sensor: No
• ADC for external current sensor: Yes

Hello @orbittechnologyx, please have a look at https://github.com/iNavFlight/inav/blob/master/docs/policies/NEW_HARDWARE_POLICY.md

Your PR is a great first step, but we also need samples to validate it works as expected.

Please reach out to me over on INAV's Discord and I can help organize the process.

• Current sensor working

• UART 1 working

• UART 2 working

• UART 3 working

• UART 4 working NO

• UART 5 working

• UART 6 working

• Video chain working Camera -> OSD - > VTX

• LEDs working

• S1-S4 correct (DSHOT and correct pin assignments)

• S5+ (servos)

Almost everything tested seems to be working well. UART 4 does not seem to be working correctly, in my testing.
I see that the pin definitions line up with one option in the datasheet.

It appears that the pad labeled TX4 is actually RX4.

Probing with a meter confirms the pad labeled TX4 is connected to PH2, UART4_RX.

Thank you very much for these tests. Unfortunately, we typed the R4 and T4 labels incorrectly. For this series, for now, we will make a note that R4 should be T4 instead of R4 and T4 should be R4, and if possible, we will even try to make corrections directly on the board.
However, we will fix this correction in the new production.
