**UPDATE** This is Version 3 V3, IMU ICM42688P, ICM42605, PWM 1~8, 10~11 What is new on the H743-mini V3 ICM42688-P+ICM42605 instead of MPU6000+ICM42605 PWM 10 & 11 instead of PWM9 & 10(V1/V1.5) Other functions, layout and components are same as previous board version. H743-mini V3 has betaflight_4.3.0 preloaded for QC ArduPilot H743-mini-V3 with ICM42688-P is supported by ArduPilot 4.2 or higher, ICM42688-P is defined as first IMU (IMU0) , ICM42605 is the 2nd (IMU1). with ArduPilot 4.2, set INS_ENABLE_MASK to 7 or default 127. It is recommended to use STM32CubeProgrammer to erase MCU and upload firmware. check this blog INAV H743-mini-V3 is not supported by INAV4.1 downloaded from configurator. pls download inav_4.1.0_MATEKH743_42688 from our website. Starting with INAV5.0, V1/V1.5/V3 will share the same firmware. BetaFlight IMU ICM42688-p is supported by BetaFlight 4.3 or higher. icm42688-p is the first IMU(default), ICM42605 is the second IMU. Target MATEKH743 in BetaFlight 4.2.x list doesn’t support ICM426XX series, You need to flash it with BF4.3_RC or latest FC Specifications MCU: STM32H743VIT6, 480MHz , 1MB RAM, 2MB Flash Board V1.0 IMU: MPU6000 (SPI1) & ICM20602 (SPI4) Board V1.5 IMU: MPU6000 (SPI1) & ICM42605 (SPI4) Board V3 IMU: ICM42688-P (SPI1) & ICM42605 (SPI4) Baro: Infineon DPS310 (I2C2) OSD: AT7456E (SPI2) Blackbox: MicroSD card socket (SDIO) 5.5x Uarts (1,2,4,6,7, Rx8) 11x PWM outputs 2x I2C (I2C1/DA1 CL1 pads, no I2C2 breakout) 1x CAN (C-H, C-L pads) 5x ADC (VBAT, Current, RSSI, VB2, CU2) 3x LEDs for FC STATUS (Blue, Red) and 3.3V indicator(Red) 1x JST-SH1.0_8pin connector (Vbat/G/Curr/Rx8/S1/S2/S3/S4) Dual Camera Inputs switch 8V power ON/OFF switch Power Vbat Input: 6.3~36V (2~8S LiPo) BEC: 5V 1.5A cont.
