ExpressLRS wiki
Flashing via Wifi
- Disconnect ESC and servos from receiver first.
- Power on receiver by 5V source. Receiver’s LED(Red) will blink slow at first, and after 20s, it should blink fast indicating it’s on Wifi Hotspot Mode.
- More detailed steps, pls refer this page.
- Target: DIY_2400_RX_ESP8285_SX1280_via_WIFI
Flashing via UART
- Disconnect ESC and servos from receiver first.
- Wire the receiver into the USB-TTL adapter, with TX on receiver connected to the Rx on the USB-TTL, and RX on receiver connected to the Tx of the USB-TTL. Wire 5V and GND of the USB-TTL to 5V and GND of the Receiver.
- Press the boot button while powering on the receiver and CRSF-PWM board, (either button on reeciver board or button on CRSF-PWM-V board). and release – the Red LED on receiver should now be solid. and Blue LED on CRSF-PWM-V should now be fast blink
- Select the target DIY_2400_RX_ESP8285_SX1280 and “UART” for Flashing Method, set your bind phrase and Firmware Options and once done, click on Build and Flash.

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️
I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well.
Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on.
Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc?
However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy.
Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book.

great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book.
I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.

Fallen for the Fallen Angel – A Guilty Pleasure Worth Every Page
Format: Kindle
There’s something deeply irresistible about a dark academia or trial-based setting, a brooding and arrogant fallen angel, and a fierce heroine with enough sass to go toe-to-toe with him. Wings So Wicked is exactly that kind of book—and I devoured it in just a couple of days.
To be fair, the plot isn’t groundbreaking. If you’re looking for something fresh and innovative in terms of storyline, this might not be it. But if your reader heart beats faster at the mere mention of enemies-to-lovers, jealousy-fueled banter, magical trials, betrayals, and forbidden tension—you’ll feel right at home. It’s like catnip for those of us with this particular weakness.
The chemistry between the leads could have used a slightly slower burn to make the tension sizzle longer, but I still found myself completely invested in their dynamic. There are moments and phrases that feel a bit cheesy or underdeveloped, but honestly? I didn’t care. The vibes were exactly what I wanted.
This book isn’t trying to reinvent the genre—it’s here to give readers like me what we crave: high-stakes magical drama, angsty romance, and the thrill of watching a badass girl and her brooding counterpart clash and spark. If that sounds like your kind of story, Wings So Wicked will hit the mark.
Here’s hoping Book 2 turns up the heat and keeps the magic alive.

my new favorite book
Format: Kindle
Ok so I never write reviews but this book was so good I felt the need to write this. Firstly your introduced to Huntyr you see her closed off hard core badass than towards the end you see the most subtle change and growth it’s amazing and the enemies to friends to lovers was just perfect, AND THE TWIST AT THE END GOT ME GOOD! You see one spicy scene the whole book but it doesn’t even MATTER BECAUSE THE BOOK WAS THAT GOOD. I’ve read 85 books in 2023-2024 so far and I’m pround to say this is my all time favorite. I’m so excited to read more of Emily Blackwoods books, this was my first time reading one of hers and I’m glad I did because HOLY!! Well done Emily well done

Fast paced romantasy you will not want to put down!
Format: Kindle
4.25 stars! I LOVED this book with similar vibes to Hush Hush, Fourth Wing, and The Serpent and the Wings of Night! It was fast paced with easy world building and will keep you turning the pages late into the night because you will not want to put it down!
Huntyr is a fierce bad@ss FMC trained to kill vampyres her entire life. She is sent on a mission to go to the academy and earn her spot into The Golden City. Upon arrival, she is forced to room with the delicious fallen angel, Wolf, who is the only one who knows about her assassin identity. The romance, the plot twists, the secrets revealed, the battles, and the tantalizing training scenes had me hooked! And that ending…. I’m holding my breath in need to know hell!

🪽 Fae, Vampyres, Fallen Angels
🪽 Academy setting with magical trials
🪽 Forced proximity and slow burn
