(Max.2A),   8V outputs stable when Vbat>=10V,  8V outputs 80% of Vbat when Vbat< 10V LDO 3.3V: 200mA VB2 pad supports Max. 69V (voltage divider 1K:20K) Static power: 200mA@5V with Betaflight,  150mA@5V with ArduPilot FC Firmware ArduPilot(ChiBiOS): MATEKH743 BetaFlight: MATEKH743 INAV: MATEKH743 (To be supported soon) Physical Mounting 20 x 20mm/Φ3mm with Silicon Grommets 20 x 20mm/Φ2mm with Silicon & Brass Grommets Dimensions:  36 x 28 x 6.5mm Weight: 7g Including 1x H743-MINI 6x Silicon grommets M4 to M3 6x Brass grommets M3 to M2 1x JST-SH1.0_8pin cable, 5cm 2x JST-SH1.0_8pin connectors           PWMPWM1~PWM13 are Dshot and PWM capable. However, mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs.If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group.

H743-MINI has betaflight firmware preloaded for QC BetaFlight Target MATEKH743 is supported since 4.3,  pls download BetaFlight firmware 4.2.x from our website. If you flash ArduPilot firmware via BetaFlight configurator.  there is a known issue that flash process will freeze at 50% if “full chip erase” is selected.   It is highly recommended to use STM32CubeProgrammer to erase MCU and upload firmware http://www.mateksys.com/?p=6905 Crossfire support only exists in “latest” 4.1, not stable 4.0.x,  if you load “latest” then Set  SERIAL7_PROTOCOL = 23,  RSSI_TYPE = 3
