+https://shop.iflight.com/BLITZ-Mini-F745-Flight-Controller-Pro2142
+
+The BLITZ Mini F745 is a flight controller produced by [iFlight](https://shop.iflight-rc.com/).
+
+## Features
+
+ - MCU: BGA-STM32F745, 216MHz
+ - Gyro: ICM42688
+ - 16Mbytes Onboard Flash
+ - BEC output: 5V 2.5A
+ - Barometer: DPS310
+ - OSD: AT7456E
+ - 6 UARTS: (UART1, UART2, UART3, UART4, UART5, UART6)
+ - I2C for external compass.
+ - 5 PWM outputs (4 motor outputs and 1 LED output)
+
+## 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 (RX, DMA-enabled)|
+|SERIAL3|TX3/RX3|UART3 (GPS, DMA-enabled)|
+|SERIAL4|TX4/RX4|UART4|
+|SERIAL5|TX5/RX5|UART5|
+|SERIAL6|RX6|UART6 (ESC telemetry)|
+
+## RC Input
+
+RC input is configured on the (UART2_RX/UART2_TX). It supports all serial RC protocols.
+
+## OSD Support
+
+The BLITZ Mini F745 supports OSD using OSD_TYPE 1 (MAX7456 driver).
+
+## PWM Output
+
+The BLITZ Mini F745 has 5 PWM outputs. The motor outputs M1-M4 are in the ESC connector housing. All 5 outputs support DShot and the first four outputs support bi-directional DShot as well as all PWM types. Output 5 is the "LED" pin and is configured for serial LED by default.
+
+The PWM are 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 11
+ - 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 Mini F745 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.
