This is the updated version for Darwin AIO. We integrated the ELRS receiver on the FC to make it easier to apply to the mini Drone. ESC adopts Bluejay firmware and is compatible with 1-3S Lipo input, and the maximum current reaches 17A.FC provides 2 sets of Uarts interfaces and at the same time provides various external devices interfaces such as SBUS, Softserial, CTR, BUZZ, RGB and so on , which perfectly solves the problem of insufficient quantity of F411 Uarts.

Learn about ExpressLRS:
ExpressLRS is an open source Radio Link for Radio Control applications, all of you can find these projects on GitHub.
it is based on the fantastic Semtech SX127x/SX1280 LoRa hardware combined with an Espressif or STM32 Processor. Using LoRa modulation as well as reduced packet size it achieves best in class range and latency. It achieves this using a highly optimized over-the-air packet structure, giving simultaneous range and latency advantages. It supports both 900 MHz and 2.4 GHz links, each with their own benefits. 900 MHz supports a maximum of 200 Hz packet rate, with higher penetration. Under 2.4GHz frequency bands,OpenTX system supports amazing 500Hz.
The Vantac ELRS Lite TX Module
Darwin Vantac ELRS Lite TX Module is based on open source project.
2.4G transmit module， the aim of the ExpressLRS 2.4G aims to achieve comprehensive performance in speed, latency and range. In addition, a convenient feature of this module is the built-in WiFi module, which enables wireless connection to upgrade firmware. Darwin Vantac ELRS Lite TX Modules are compatible with remotes with lite-style module bays.
The specifications of the TX Module:
Packet refresh rate: 50HZ/100HZ/150HZ/250HZ/500HZ
RF output power:10mW/25mW/50mW/100mW/250mW/500mW
Frequency bands: 2.4GHz ISM
Input voltage: 5V~12V
USB port: Type-C
Darwin ELRS 2.4G TX Module use lite-style TX Module bays and it is compatible with the following remote control:
Right away, this is the best 65mm Whoop I know. Not even close.
I ordered two, one is more or less stock, just the PEEK motor screws and V3 cockroach. The second is upgraded to 0702 27000kV but will go back because I like the 25000kV more because of smoother throttle response and perfect betaflight tune.
Now the but:
1. On both quads I had to replace the BeeEye for a spare one because both are out of focus.
2. the yellow props were way too loose and very brittle. I lost two on my maiden. Black, blue and red are very tight (too tight for such a fragile prop) but if you get them on without bending them, they will last.
3. why does the quad not come with the lighter frame right away?
4. PH2.0…. You know the drill.
On that price point, even after the frame and PEEK upgrade I can forgive these quality issues. Especially considering the great tune and quality FC and motors. But be sure to order a replacement cam and props right away.
This was kind of a late night lark. I'd seen this upgrade for the Mk3 for a while and pondered whether it was a gimmick or not, and I'm pleased to say it's a genuinely good upgrade. It has reduced the noise of my Mk3 considerably. I haven't noted any significant increase in print quality, but the old drone of the bed is gone and that's completely worth it.
