N.B: Attention: Before powering on, please make sure to reliably connect the antenna, otherwise it will burn when powered on.

The JHEMCU VTX20-600 is an ultra-lightweight 5.8GHz analog video transmitter engineered for micro, 3-inch, and compact freestyle FPV builds where space and weight are critical. Weighing just 3 grams with a standard 20×20mm stack mounting pattern, it delivers up to 600mW of switchable RF output across 40 channels, supports IRC Tramp telemetry control for OSD power/channel adjustments, and provides a regulated 5V/1A BEC output to power an FPV camera directly.

Features:

Adjustable output power across six levels (PIT / 25mW / 100mW / 200mW / 400mW / 600mW) to accommodate indoor flying, multi-pilot race events, and mid-range outdoor freestyle.
Built-in PitMode enables bench testing and pre-flight configuration without interfering with active pilots on nearby frequencies.
Supports IRC Tramp protocol for direct VTX channel, band, and power switching via Betaflight OSD and radio transmitter sticks.
Wide 7V–26V (2S–6S LiPo) input voltage range with an onboard 5V/1A filtered BEC output to cleanly power FPV cameras.
Ultra-compact 27×27mm footprint with 20×20mm M3 mounting holes fits seamlessly into tight micro and 3-inch flight controller stacks.
Dual connectivity options allow installation using either the included 6-pin 1.0mm JST plug harness or direct solder pads.
