Toxikrocks 0 Posted January 8, 2017 Report Share Posted January 8, 2017 I would like to attach some leds that I can turn on and off. Can I use the pins to attach a led strip and control it via the controller? Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted January 8, 2017 Author Report Share Posted January 8, 2017 Sorry, but I don't know of any easily accessible pins that can be used for that. Quote Link to post Share on other sites
Toxikrocks 0 Posted January 8, 2017 Report Share Posted January 8, 2017 What would be the next best thing? Solder it up to the buzzer so I can control it from the transmitter? Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted January 8, 2017 Author Report Share Posted January 8, 2017 If you don't mind giving up the buzzer you could re-purpose it to control some LED's. But the buzzer signal is 5V and can only drive about 30mA maximum. If you only need to turn on a couple low current LED's then the hack is relatively simple. Just remove buzzer, add LED(s) with current limit resistor(s). But to operate some bright LED's (that need different voltage and/or need more current) you have to add a driver circuit to the buzzer signal. For example, you could swap out the buzzer with a MOSFET SSR IC, such as something based on a VO14642A. Then this SSR could handle up to 2A directly from the 2S battery pack. 1 Quote Link to post Share on other sites

Should be here soon. Thanks Mr.RC-Cam for all the great work. I should be receiving my minimosd tomorrow at which point I'll be adding my first hack to my Rodeo 150. For my second hack I'm thinking of adding a servo to adjust the camera angle. It might be because I'm quite new to FPV flying, and maybe I'll get used to it, but I feel like it would be nice to be able to adjust the camera angle on the fly. When flying at a low angle of attack (indoors) I want the camera to point mostly forward. When flying outdoors and I have some more space to push it, the camera obviously needs to point more up. I can see on Cleanflight CLI that there are additional modes for Servo1-3. I'm thinking of using one of these for my mini-gimbal hack I couldn't find anyone that has tried adding a servo to the Walkera FC. Can somebody possibly point me in the right direction to figure out which MCU pins are used for these additional servo outputs? Maybe someone has a standard SPF3 and could test the connections between the servo headers and the MCU pins? As a last resort I will have to configure the servo in Cleanflight and test each of the impossibly small pins on a scope for a matching signal. Thanks, x6 Quote Link to post Share on other sites

Here's a discussion that has some basic tips for connecting a servo to a SPRacing F3 flight controller:https://www.rcgroups.com/forums/showthread.php?2598878-Seriously-Pro-Racing-F3-servo-tilt Quote As a last resort I will have to configure the servo in Cleanflight and test each of the impossibly small pins on a scope for a matching signal. You should plan on doing that; From my experience hacking the Rodeo, it's doubtful that the proprietary Walkera FC has a dedicated header for the "spare" servo signals. If they did it then you have essentially won the state lottery. FYI, tilt servos are not something expected on a racing style drone. The task is easily handled by manually adjusting the camera angle before flight. But it's a hobby, so do what makes YOU happy. Be sure to post photos of how you crammed a servo controlled tilt mechanism into your tiny Rodeo -- I'd like to see that magic! Quote Link to post Share on other sites

Having another look at the camera mount I'm starting to doubt any servo would fit in there. I am getting used to the angle, but now I'm getting very annoyed that the camera angle keeps changing whenever I crash (which is quite often). A gimbal would keep it in place or I could at least correct the angle after a crash. I finally got my micro minimosd today so when I have everything disassembled I'll take some measurements and see if there is any hope for a gimbal hack. In the mean time, here's the STL file for replacement landing skids if anyone is interested. Rodeo 150 Landing Skid Rev4.zip Quote Link to post Share on other sites
jm12 0 Posted January 25, 2019 Report Share Posted January 25, 2019 Thanks to Me.RC-Cam and G-unit. I bought a Rodeo 150 and an XSR-M receiver thinking that both form factor and connector were interchangeable with stock- not quite. This thread was the only place on the internet where I could find details on pin layout and it was relatively easy from there. Did anyone ever managed to get telemetry going? I ended up just taping off the smartport lead but I would love to get it hooked up if there's a successful example out there to follow. Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted January 25, 2019 Author Report Share Posted January 25, 2019 I don't know of anyone that has connected the Rodeo to a Smart Port R/C Rx, but that shouldn't stop you from trying. My OSD hack information shows how to access the FC's UART2:https://www.rc-cam.com/forum/index.php?/topic/4101-diy-walkera-rodeo-150-minimosd-installation/&do=findComment&comment=28599 Then you would use the CleanFlight Configuration app to configure the FC to enable the Smart Port function on UART2.

jm12 0 Posted January 25, 2019 Report Share Posted January 25, 2019 Thanks, I may give this a shot- if I do I will report back. This world is very new to me so I don't have much of a foundation to go off of thus the reluctance to go poking about without concrete precedent. I think G-unit had tried but I don't know if he ever got things working. Quote Link to post Share on other sites
Tmo 0 Posted September 15, 2020 Report Share Posted September 15, 2020 I am wondering how to replace the stock receiver with a frsky receiver? Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted September 16, 2020 Author Report Share Posted September 16, 2020 The basics on installing a different receiver are shown in this guy's video: 1 Quote Link to post Share on other sites
Tmo 0 Posted September 16, 2020 Report Share Posted September 16, 2020 I can not seem to find a pinout for the rodeo 150 external Rx connector. The best information I could find so far has me to believe that the top 3 pins (from left to right) are GND, V+ and signal (maybe PPM and SBUS). I don't know what the bottom 3 pins are. Does anyone have a pinout ? Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted September 18, 2020 Author Report Share Posted September 18, 2020 The video shows the receiver pinout at the 3:00 minute mark. What it shows matches the photo you posted. The bottom row is somewhat of a mystery (the manual calls it a 5V power output). Quote Link to post Share on other sites
