The classical ultralight F4 1S brushless FC comes back with SPI ExpressLRS 2.4G receiver.

Now the default firmware for F4 1S 5A AIO Brushless Flight Controller (ELRS 2.4G) is updated to Betaflight V4.3.0 RC6, which supports ELRS V2.0. Please check the below link to download the firmware.

Download the betaflight_4.3.0_BETAFPVF4SX1280_ELRS2.0.hex

SPECIFICATIONS OF FC

  • CPU: STM32F411CEU6 (100MHZ)
  • Six-Axis: ICM-20689/MPU-6000
  • Built-in Receiver: SPI ExpressLRS 2.4G
  • Receiver antenna: 2.4GHz SMD ceramic antenna
  • Size: 29mm x 29mm, fully mounting pattern compatible with the whoop frame in the current market
  • Firmware version: betaflight_4.3.0_STM32F411_norevision
  • OSD: Built-in BetaFlight OSD
  • Recommend VTX: >=200mW, like BETAFPV M03 350mW VTX or TBS Unify VTX
  • Power Cable: 55mm, with BT2.0 connector
  • Weight: 3.13g (no power cable included)

SPECIFICATIONS OF ESC

  • Power supply: 1S
  • Current: 5A continuous and peak 6A (3 seconds)
  • Support BLHeliSuite programmable
  • Factory firmware: O_H_5_48_REV16_8.HEX
  • Signal Support: D-shot150, D-shot300, D-shot600, Oneshot125, Multishot, PWM

Something you should know to protect the ESC SMD ceramic antenna.

  • Recommend using BETAFPV Camera Canopy, which reserves sufficient space between Camera and ESC. Therefore, the SMD ceramic antenna will be protected very well.
  • Please make sure there is enough space between the camera and the antenna. If the camera position is too low, it will damage the antenna. So the whole FC should be reversed 180 degrees for installation and all motor positions should be reversed too.
  • The antenna shouldn't be exposed. It will be fragile without canopy protection.

Betaflight Firmware and CLI

Since Betaflight has not yet released the official firmware that could support the SPI ExpressLRS protocol, the current version is the Beta version. Please use the firmware and the CLI dump file below to recover the FC board if needed. Betaflight will update its official target soon. Please feel free to contact us if you have any issues with this Beta version Firmware.

It is normal that there is no option on Betaflight Configurator Receiver. As is shown below, the checkbox is blank.

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

The firmware BTFL_4.3.0_BETAFPVF4SX1280_0265565fa uses external GPIO interrupt triggers to process ELRS data reception, increasing the stability of the signal link. Now it can perfectly support LiteRadio 2 SE 500Hz link and modify the accuracy of signal strength. 

The new CLI file is named BTFL_cli_F4 5A ELRS_NEWPlease check.

Note: This firmware supports only ELRS 1.0.0, 1.0.1, 1.1.0, 1.2.0, 1.2.1.

      Bought on Amazon, but they will not let me write review!

      Amazon took away my ability to review for no reason, but betaFPV deserves a good review.
      I absolutely LOVE flying this flight controller. The latency when using this ELRS on just my literadio 3 is outstanding. It feels like crashing isn't possible haha!
      I do have one issue with it, and I am not sure if it is the FC or the betafpv MO1vtx camera kit but I cannot get smart audio to work with soft serial RX. I have not tried just soldering the SA wire into the Uart at the top and using it that way but I may go that route. Smart audio comes on and gives the statx no signal failure... but it DOES see the wire.

      Otherwise this thing is SUPER FUN! Runs really nicely on new version of betaflight. The prop wash and stability is excellent with stock filter settings. I am feeling no need to change it.

      Current Sensor

      The correct current Sensor amp Meter value in Betaflight is 1175 +/- 5 not 179.

      really good, one nit

      I've been racing with these boards for a few months, and overall I really like them. I was running BF 4.3 RC3, and have started updating them to RC5. Overall they fly well.

      My only complaint is that they seem overly susceptible to "drunk gyro", so they sometimes don't fly well after crashing into a gate. I'm hoping that's something that can be addressed in firmware vs hardware - if so I'd give it 5 stars for sure!

      Good for ultralight builds

      I build a 75mm Whoop with 0702 Motors and a super silent 35g 3" with 1103/8000 Motors. Really cool!
