HelloRadioSky V15 Ultra FPV ELRS Radio Transmitter

HelloRadioSky V15 Ultra FPV ELRS Radio Transmitter

The HelloRadioSky V15 Ultra is more than a radio. It’s a full bench lab built into an EdgeTX transmitter. Alongside a 4.3″ colour touchscreen, RDC metal gimbals and an H7 processor, the V15 adds a dedicated EXT test port and HRS Tools firmware so you can detect receiver protocols, view waveforms, test servos and spin up ESCs straight from your radio. Add a 1-6S cell meter and 20W PD fast charging with live power readout, and it covers most of the tools you’d normally carry to the bench or the field.

Features

• 4.3″ IPS colour touchscreen running EdgeTX ColorLCD
• RDC metal gimbals for a smooth, precise feel
• H7 processor
• Dual-band antennas and translucent body
• EXT multi-function test port (GND / +5V / SIG) with HRS Tools built in
• Auto Measure: automatically detects PWM, PPM, SBUS, CRSF/ELRS, SUMD, DJI RS and MAVLink, then opens the matching live readout
• Pulse Scope: digital waveform view showing pulse width, period, duty cycle and edge rate
• Servo Tester: Standard, Wide, Digital and Heli servo types with Manual, Auto sweep and Stick modes
• DShot Tester: DShot150 and DShot300 output with ARM gating, throttle control and beep commands
• 1-6S Battery Meter: per-cell voltage bars, pack voltage, SOC and cell imbalance (dV) via balance lead
• 20W USB-C PD fast charging with live voltage, current, wattage and SOC display
• SIG overvoltage protection: tests are blocked if the signal line is above 5V
• Approx. 1A overcurrent cut-off on the +5V output
• Trainer master support: locked receiver channels (CH1-8) can feed trainer input
• Bilingual firmware (English and Chinese), flashed via simple UF2 drag-and-drop
