Welcome to the club! Yes there is no book with everything explained from A to Z. But you still will have to read a lot. There is TONs of information on the net. Also it is advised to join the RCGroups.com community. Check the Oscarliang.com – he has a lot of guides for beginners. Joshua Bardwell on Youtube is also very informative.

I wish someone would write a book that takes new folks by the hand and walks them through the “how To” for controllers and explains the terminology. I don’t know how to hook up my Spektrum race receiver, set arming switches, actually get the computer ton talk to the board, and understand the what and how of the features. Yes there is U-tube but not truly helpful because it assumes the audience has some level of knowledge. So if some enterprising person would go “back to the basics” with an instructional video for this I and others would be extremely grateful.

i used this same receiver with 1.0 and betaflight 3.2 on an omnibus f4. I connected the receive to the sbus pin, set rx on uart 6, serial based rx and spektrum Bidir SRXL in betaflight and it works.

i’ve tried everything with this board and cannot get it to work. closest i’ve come was using the sbus input with rx on uart1. this sometimes gives me erratic receiver perfomance and the rx always tries to rebind on power up. i tried a 2nd rx with the same results.

any suggestions?

best regards

Thanks, ZzyzxFPV, for detailed info. I’ve asked GetFPV.com for user manual and more information, but only got sorry no manual and no more information. Just a suggestion to use similar boards as example… ??

I think you can wire XSR s.port to either TX3 or TX6. I’ve got it working with TX3. But (big but here), there is no inversion on TX3 or TX6 (only on TX1, labelled SBUS). F4 boards do not have hardware inversion, so you can’t invert from Betaflight. The fix is to tap into the non-inverted s.port signal on the XSR. See this guide: https://blck.mn/2016/06/smartport-the-frsky-xsr-and-betaflight/ It looks hard at first, but was fairly easy with a fine point solder tip.

Thanks, yeah this board largely follows the Omnibus F4 pattern, so I’ve found most guidance for the Omnibus F4 applies to this Lumenier F4 AIO board, too. The only weirdness I found was having to tap into the non-inverted s.port pin on the XSR to connect it to an available UART (3 or 6), but that seems to be true on any F4 board since there is no hardware inversion. Cheers

Thanks Montis for the reply. Would you wire up XSR’s s.port to TX3 instead? Any ideas/suggestions would be appreciated.

S6 pad is most likely PWM6, that can be remapped to any serial output. I will try to get better answer later.

PWM5 and PWM6 outputs can be remaped for soft serial by CLI commands:
resource motor 5 none
resource motor 6 none
resource led_strip none
resource serial_tx 11 a1
resource serial_tx 12 a8
