|
|
|
||
|
|
The Blitz F7 AIO is a flight controller produced by [iFlight](https://shop.iflight-rc.com/).
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
## 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, DMA-enabled)|
|
||
|
|
|SERIAL2|TX2/RX2|UART2 (DJI connector RX, DMA-enabled, TX is on the back side of board)|
|
||
|
|
|SERIAL3|TX3/RX3|UART3 (Alt RX or GPS, DMA-enabled)|
|
||
|
|
|SERIAL4|TX4/RX4|UART4|
|
||
|
|
|SERIAL7|TX7/RX7|UART7|
|
||
|
|
|
||
|
|
## 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 BLITZ Whoop F7 AIO supports OSD using OSD_TYPE 1 (MAX7456 driver).
|
||
|
|
|
||
|
|
## PWM Output
|
||
|
|
|
||
|
|
The BLITZ Whoop F7 AIO has 4 PWM outputs internally connected to its 4-in-1 ESC. The pads for motor output are M1 to M4 on the board. All 4 outputs support bi-directional DShot and DShot, as well as all PWM types. The default configuration is for bi-directional DShot using the already installed BlueJay firmware.
|
||
|
|
|
||
|
|
The PWM are in in two groups:
|
||
|
|
|
||
|
|
- PWM 1-4 in group1
|
||
|
|
- PWM 5 in group2
|
||
|
|
|
||
|
|
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 and a current sensor input tied to its 4 in 1 ESC current 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 10.9
|
||
|
|
- BATT_CURR_PIN 13
|
||
|
|
- BATT_CURR_MULT 50
|
||
|
|
|
||
|
|
These are set by default in the firmware and shouldn't need to be adjusted
|
||
|
|
|
||
|
|
## Compass
|
||
|
|
|
||
|
|
The BLITZ Whoop F7 AIO does not have a builtin compass, but you can attach an external compass to I2C 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.
