JHEMCU G474ELVTX 1-2S 5 in 1 Tiny Whoop FPV AIO

Friendly reminder: Due to the high integration of this PCB, the overall solder joints are relatively small.  Those without soldering skills, those unfamiliar with soldering irons, or complete beginners, or those unfamiliar with Betaflight should proceed with caution.

The JHEMCU G474ELVTX uses an STM32G474 processor, ICM42688-P gyroscope, integrated OSD, built-in 8MB black box, built-in 5V/1.5A BEC, built-in independent ELRS 2.4G receiver, built-in VTX 5.8G 400MW video transmission module, and supports 1-2S 12A brushless ESCs (four channels). This circuit board does not have a barometer module. If using 1S power and experiencing difficulty starting the motors, please adjust the startup power value to an appropriate level to ensure proper startup. The video transmission on this AIO does not have the Low Power Disarm function enabled by default (this means that when unlocked, the video transmission is at maximum power, and when locked, it's at minimum power, which can reduce the PCB temperature during tuning). If you don't use the built-in ELRS, it also supports external SBUS receivers.
