HappyModel ELRS F4 2G4 AIO 5in1 Flight Controller SPI 2.4GHz ELRS RXThe worlds first AIO 5in1 F4 flight controller with integrated SPI 2. 4GHz ExpressLRS receiver has been launched. The flight controller integrates SPI controlled 2. 4GHz ExpressLRS receiver, Dshot protocol 4 in 1 ESC, 5. 8GHz 40ch video transmitter and Betaflight OSD. Ultra small size and ultra stable remote control range can improve the range of the original SPI receiver. And because the 2. 4GHz ExpressLRS receiver is equipped with the SX1280 radio

The world’s first AIO 5in1 F4 flight controller with integrated SPI 2.4GHz ExpressLRS receiver has been launched. The flight controller integrates SPI controlled 2.4GHz ExpressLRS receiver, Dshot protocol 4-in-1 ESC, 5.8GHz 40ch video transmitter and Betaflight OSD. Ultra-small size and ultra-stable remote control range can improve the range of the original SPI receiver. And because the 2.4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity, high packet rate and low latency, this flight controller is the one that all Race/Freestyle pilots needed. It is suitable for use in Tiny whoop Race or Toothpick Freestyle, and can also be used in 1S ultra-lightweight Nano Long Range platform.

 

 

Notes: Due to the high-power VTX onboard, the temperature of the AIO flight controller will be relatively high in the standby state, and the camera signal may be lost after a couple of minutes standby. This is a normal phenomenon, please don’t worry. We strongly recommend using a fan to cool down when setting up the flight control. Please make sure the vtx antenna was plugged before power for the AIO flight controller.

ELRSF4 2G4 will work with the ELRS 2.4Ghz TX module which was updated V1.0.0 or latest version firmware.  So no need to flash old RC3 version TX module firmware.

Bind procedure:

  1. Power the flight controller by connecting USB. Please make sure that the port driver of the flight controller is correctly installed on the computer, then open Betaflight Configurator(Latest version) to connect, enter to the “receiver” interface, and then click “Bind Receiver”, the red LED at the bottom of the flight controller will flash quickly, which means that the SPI ELRS receiver enters the bind mode. There is another way to make the receiver enter the bind mode: after connecting to the Betaflight configurator, move to the CLI interface and enter “bind_rx” in the command line.
  2. After correctly connecting the ES24TX or ES24TX Lite/Slim module or DIY 2.4G ELRS TX module to your Opentx radio transmitter, copy the latest version of ELRS.LUA file to the SD card in the remote controller. The directory is “SD Card/Scripts/tools”, Then run ELRS.LUA and upgrade the specified TX frimware through Wifi, and then click “bind” to link with the SPI ExpressLRS receiver.  The Red LED will blinking slowly, this means the bind is successfully. Note: You need to adjust the Packet Rate to 500Hz from the ELRS interface of your radio controller before binding.
  3. After the binding is successful, please re-power for the radio transmitter and then the Red LED at the bottom of the flight controller will getting to be solid, and the telemetry can be received at the same time.
  4. The meaning of the LED status of the SPI receiver: the LED is getting to be solid, indicating that the bind is successful or the connection and communication is normal, the LED flashing quickly indicates that the receiver is in binding mode, and the LED flashing slowly indicates that the there is no signal received from the radio controller.

Firmware and diff document download link

Notes: Since Betaflight has not yet released the official firmware that could supports the SPI Expresslrs protocol, the current version is the Beta version(Target:CrazybeeF4SX1280). Betaflight will update to their official target soon. Please feel free to contact with us if you have any issues with this Beta version Firmware.

Please change the “PID loop frequency” to “4KHZ” , sometimes it would make the SPI receiver not working correct while the value is “8KHZ”


If find buzzer is not working , please go to CLI command and enter the following code

set beeper_inversion = ON
set beeper_od = OFF

Great Bulk Pack of Disposable Spoons for Everyday Use
The Amazon Basics Disposable Everyday White Spoons are a very practical and affordable option for parties, offices, events, break rooms, or everyday household use. The large 1000-count pack is especially convenient because it lasts a long time and helps reduce the need for constant restocking. The spoons are lightweight but still sturdy enough for most everyday foods like cereal, yogurt, desserts, soups, and side dishes. They don’t feel overly flimsy for normal use, which is important for disposable utensils. I also like the clean white design because it works well for casual gatherings, parties, school events, picnics, and office lunches. Having such a large quantity on hand is very helpful for busy households or larger events. The spoons are individually easy to grab and separate from the bulk packaging, making storage and use simple and convenient. Overall, this is a reliable and cost-effective bulk pack of disposable spoons that works well for everyday meals, gatherings, and large events.

Bulk spoons finally broke my bad habit
We used to grab those little 20 packs from the grocery store every couple weeks and it felt like I was always running out at the worst time. When I saw this giant box I got pretty stoked and pulled the trigger right away. They are exactly what you would expect from basic disposable spoons. Solid enough for everyday stuff like yogurt, ice cream, or takeout without bending too much. Nothing fancy but they get the job done every time. At about three cents each it feels like a much smarter way to buy them. Now that we have a thousand of them sitting in the pantry I catch myself using them way more often instead of washing silverware for small snacks. This box should easily last us a couple years and I am already glad I do not have to make those annoying little trips anymore.

BIG box of spoons
This is one big box of white plastic spoons. Probably more than you need for home use. I’ll probably end up donating most of these to my kid’s school for the teachers lounge. The spoons are not packaged in smaller boxes or bags inside. The quality is pretty good for “everyday” spoons. Compared to the spoons I get at my local grocery store which feel more like premium plastic ware, these are smaller and made of a softer plastic. I wouldn’t call them flimsy, but they are definitely not as sturdy as the other spoons. As far as value goes, I don’t think you can find a better deal for bulk plastic spoons (currently about $30 for 1000)

Huge box of spoons that actually hold up!
My patience started wearing thin as a result of having to always keep buying spoons due to all the cereal and yogurt that the volunteers have each morning. Finally, I decided to buy these gigantic boxes just to be over with it once and for all. These spoons are surprisingly durable given the extremely low price and the fact that they are just disposable plastic utensils. I tried using one on some dense frozen ice cream yesterday evening, and the handle did not even flex at all, let alone break. This product comes packaged in a fairly frail cardboard box which makes it occupy quite a bit of floor space in the pantry. Nevertheless, I find it completely worthwhile.

They will be perfect for the party and clean up will be very easy. Overall, I am happy that I got these spoons. I would recommend them to anyone who needs a bulk quantity of good quality spoons, and I don't have anything bad to say about them at all.
