# iFlight Beast H7 v2 55A AIO Flight Controller |
||||
|
||||
https://shop.iflight-rc.com/Beast-H7-V2-55A-AIO-MPU6000-25.5-25.5-pro1588 |
||||
|
||||
The Beast H7 AIO is a flight controller produced by [iFlight](https://shop.iflight-rc.com/). |
||||
|
||||
## Features |
||||
|
||||
- MCU: BGA-STM32H743 |
||||
- Gyro: BMI270 |
||||
- 16Mb Onboard Flash |
||||
- BEC output: 5V 2.5A |
||||
- No Barometer |
||||
- OSD: AT7456E |
||||
- 5 UARTS: (UART1, UART2, UART3, UART4, UART7) |
||||
- I2C for external compass. UART3 pins are used for I2C (BRD_ALT_CONFIG=1) |
||||
- 5 PWM outputs (4 motors and 1 LED) |
||||
|
||||
## Pinout |
||||
|
||||
 |
||||
|
||||
## UART Mapping |
||||
|
||||
The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the |
||||
receive pin for UARTn. The Tn pin is the transmit pin for UARTn. |
||||
|Name|Pin|Function| |
||||
|:-|:-|:-| |
||||
|SERIAL0|COMPUTER|USB| |
||||
|SERIAL1|RX1/TX1|UART1 (DJI connector)| |
||||
|SERIAL2|TX2/RX2|UART2 (DJI connector, TX is on the back side of board)| |
||||
|SERIAL3|TX3/RX3|UART3| |
||||
|SERIAL4|TX4/RX4|UART4| |
||||
|SERIAL7|TX7/RX7|UART7 (GPS)| |
||||
|
||||
All UARTS support DMA. |
||||
|
||||
## RC Input |
||||
|
||||
RC input is configured on the (UART2_RX/UART2_TX) pins which forms part of the DJI connector. It supports all RC protocols. |
||||
|
||||
## OSD Support |
||||
|
||||
The Beast H7 v2 AIO supports OSD using OSD_TYPE 1 (MAX7456 driver). |
||||
|
||||
## PWM Output |
||||
|
||||
The Beast H7 AIO supports up to 4 PWM outputs. The pads for motor output ESC1 to ESC4 on the above diagram are for the 4 outputs. All 4 outputs support DShot as well as all PWM types. |
||||
|
||||
The PWM are in in two groups. |
||||
|
||||
Channels within the same group need to use the same output rate. If |
||||
any channel in a group uses DShot then all channels in the group need |
||||
to use DShot. |
||||
|
||||
## Battery Monitoring |
||||
|
||||
The board has a builtin voltage sensor. The voltage sensor can handle up to 6S |
||||
LiPo batteries. |
||||
|
||||
The correct battery setting parameters are: |
||||
|
||||
- BATT_MONITOR 4 |
||||
- BATT_VOLT_PIN 12 |
||||
- BATT_VOLT_MULT around 10.9 |
||||
- BATT_CURR_PIN 13 |
||||
- BATT_CURR_MULT around 28.5 |
||||
|
||||
These are set by default in the firmware and shouldn't need to be adjusted |
||||
|
||||
## Compass |
||||
|
||||
The Beast H7 v2 AIO does not have a builtin compass, but you can attach an external compass to I2C pins. Default configuration does not have I2C bus enabled. You need to set BRD_ALT_CONFIG=1 to make I2C use RX3/TX3 pins. |
||||
|
||||
## NeoPixel LED |
||||
|
||||
The board includes a NeoPixel LED on the underside which is pre-configured to output ArduPilot sequences. This is the fifth PWM output. |
||||
|
||||
## Loading Firmware |
||||
|
||||
Initial firmware load can be done with DFU by plugging in USB with the |
||||
bootloader button pressed. Then you should load the "with_bl.hex" |
||||
firmware, using your favourite DFU loading tool. |
||||
|
||||
Once the initial firmware is loaded you can update the firmware using |
||||
any ArduPilot ground station software. Updates should be done with the |
||||
*.apj firmware files. |
