![DOGCOM 5200mAh 6S 120C 22.2V LiPo Battery QS8 [DG]](http://my.fpvfaster.com/cdn/shop/files/5200mAh120C6S22.2V_300x300.jpg?v=1719899749)
Matek H743-SLIM V4 Flight Controller 30.5x30.5mm
What is new on the H743-slim-V4
- Increase the output current of BEC5V from 2A to 2.5A, and raise the filtered VBAT current from 1A to 2A.
- Add TVS protection on Input voltage
- Add protections on more MCU I/O.
- Replace DPS310 with DPS368(environmentally protected against water (IPx8), dust & humidity)
- Other functions, Pins/Pads layout are same as previous board version.
*Update: We have been starting to use IMU ICM42605 instead of ICM20602 in new batch of H743 Series because of ICM20602 shortage.
