SuperX ELRS V2.0: The 'Do It All' Board for People Who Hate Wiring

Look at you, trying to build a 1S toothpick that weighs less than a single Walkers crisp. You want power, you want range, but you definitely don't want to spend four hours squinting at a soldering iron trying to bridge pads the size of a dust mite. Enter the SuperX ELRS V2.0—the Swiss Army knife of flight controllers, minus the useless toothpick and the tiny scissors that never actually cut anything.

Why You Want It

This isn't just a flight controller; it's a 5-in-1 miracle of engineering (or black magic, we aren't sure). We’ve crammed an F411 MCU, a BMI270 gyro, 5A ESCs, a 400mW OpenVTX, and a UART-based ExpressLRS receiver onto a 25.5mm board. It’s perfect for those who want to spend more time crashing into trees and less time wondering why their VTX isn't talking to their FC. It’s light, it’s 1S, and it’s probably smarter than your primary school math teacher.

Specs

• MCU: STM32F411CEU6 (100MHz, 512K Flash - fast enough to fix your bad lines)
• Sensor: BMI270 (SPI connection, keeps things smooth while you're trembling on the sticks)
• Mounting: 25.5mm x 25.5mm (The industry standard, unlike your weird DIY frame)
• Power Input: 1S LiPo/LiPo HV (2.9V-4.35V)
• ESCs: Built-in 5A Continuous, 6A Peak (Bluejay v0.19.2 pre-flashed because we love you)
• VTX: Onboard 5.8G OpenVTX (0mw to 400mw via MSP control)
• Receiver: UART ExpressLRS v3.0 (2.4GHz with an enameled copper wire antenna)
• OSD: Betaflight OSD (SPI Control)
• Sensors: Built-in Voltage (Scale 110) and Current (Scale 1175) meters

In the Box

• 1x SuperX ELRS V2.0 AIO Board
• 1x U.FL Antenna (Keep it away from the props, genius)
• Necessary mounting hardware (to lose in your carpet)

Compatibility

Works flawlessly with ExpressLRS V3.x.x TX modules. If you're still using V2, please join us in the present day. Supports 1S batteries and standard 25.5mm whoop or toothpick frames.

Highlights

• UART ELRS: None of that SPI ELRS nonsense. Update via WiFi or passthrough like a civilized human.
• 400mW VTX: Enough power to blast through two walls or one very thick hedge.
• Bluejay Ready: 48KHz PWM frequency out of the box. Smoother than a buttered slide.

Notes

Recommended ESC Startup power: Min 1100 / Max 1200. Firmware target for the board is HappyModel AIO 2.4GHz RX+VTX. Don't flash the wrong target unless you enjoy owning a very expensive green paperweight.

Disclaimer

Warranty doesn't cover 'I flew it into a pond' or 'I soldered it with a blowtorch.' Fly responsibly, or at least film the crash.

Still Here?

If you're still reading, you're either a bot or really indecisive. This is the 1S AIO you need for your next ultra-light build. Buy it, fly it, break it, repeat. #TinyWhoop #ELRS #Happymodel #FPVLife #AIOFlightController
