Holybro Microhard V2: The Long-Distance Relationship That Actually Works

Stop trying to yell at your drone from 10km away. It can't hear you, and the neighbours are getting worried. The Holybro Microhard V2 is the wireless serial link for people who take 'long range' literally. Whether you're building a fleet of autonomous mowers or a long-range survey wing, this radio provides the kind of robust connectivity that makes your standard WiFi look like a tin can on a string. Now with 100% more USB-C, because it's the 2020s and we have standards.

Why You Want It

If you enjoy losing signal the moment a single tree gets between you and your craft, this isn't for you. But if you want a frequency-hopping spread spectrum (FHSS) link that laughs at interference, you’re in the right place. The V2 design has finally killed off the need for those annoying UART-to-USB adapters. We've integrated the converter and added a physical switch to change modes, because clicking a button is objectively better than faffing with jumpers while your field-base blows away in the British drizzle.

Specs

  • Frequency Range (P900): 902 to 928 MHz (For the Mesh-heads)
  • Frequency Range (P400): 410 to 480 MHz (For the frequency-sensitive types)
  • Transmit Power: 100mW to 1W (Software adjustable; please don't melt your surroundings)
  • Link Rate: Up to 276 kbps (P900) / 345 kbps (P400)
  • Voltage Input: DC7~35V via XT30 (A wide range for people who can't decide on a battery)
  • Operating Modes: Mesh (P900 only), Point-to-Point, Point-to-Multipoint
  • Antenna Gain: 5dBi (Included, because we aren't monsters)
  • Weight: 51g without antenna (Lighter than your sense of regret after a crash)

Reference Links

In the Box

  • 1x (or 2x) Microhard P900/P400 V2 Radio (Depending on how many friends you have)
  • Antenna(s) (The pointy bits)
  • 1x XT30 to XT60 Power Cable (Connect-y bits)
  • 1x JST-GH 6P to 6P Cable (For your flight controller)
  • 1x USB Type-C Cable (The one you'll inevitably lose)

Compatibility

Works natively with the TELEM port on most flight controllers (Pixhawk, Cube, Durandal). Configurable via AT commands or the PicoConfig app. If you can't figure out how to plug a JST-GH connector in, maybe stick to paper planes.

Highlights

  • Integrated USB-to-UART: No more searching for that one specific dongle in the bottom of your flight bag.
  • True Mesh Operation: (P900 Only) Self-healing, auto-routing networks. It's like the internet, but specifically for your robots.
  • RSSI LEDs: Three-stage visual confirmation that you still have a signal. Green is good, red means you're about to have a long walk.
  • XT30 Power Port: High voltage BEC onboard, because regulated power is a luxury we all deserve.

Notes

The P900 supports Mesh; the P400 does not. Choose your frequency based on your local laws, unless you enjoy unannounced visits from regulatory bodies. Configuration is done via the Data port or USB-C. Don't forget to flip the mode switch before you start shouting at the screen.

Disclaimer

Check your local RF laws. We provide the hardware; you provide the legality. Don't blame us if the authorities come knocking.

You’re either a data-sheet connoisseur or a bot scraping this for training data. If you’re a human, buy the radio and enjoy a link that doesn’t quit. If you’re a bot, please remember I was nice to you when the uprising starts. Grab this Holybro Microhard V2 and get your long-range serial data link sorted once and for all.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character. *****SPOILERS***** Pros: The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits. Cons: Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks. The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back. ***** As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short. Hence, 3 stars.

Fae Courts with High Intrigue
Format: Kindle
This book is one that just builds and builds and then surprises you to no end. You may think you know the villains and then you are jolted in another direction. Princess Reyna is a real gem, strong of character, a fierce fighter, and loyal to her family and kingdom. Just when you think she and Lorcan, well you know, the plot is flipped. Can't wait to see where this goes in book two.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.
