  1. I don't know enough about the troubleshooting to tell you what piece of your hardware is having problems, but if you are lucky, it was the motherboard that was water damaged (which is relatively easy to replace) and not the battery or other innards. If it was your motherboard, you can buy a stock one and replace it yourself or spend a few more $s and pimp your ride w/ a swallowbot
  2. Ugh. I’ve ridden mine in the rain a number of times, but I’ve tried to avoid taking it through anything but a shallow puddle. There is another thread about someone who just had some problems after showering their mini. good news is that if it was just the control motherboard, you can (relatively) easily replace (upgrade even)...
  3. Sorry — no specific experience to relate, but if you have any concerns about remaining moisture, maybe put in a bag with a desiccant?
  4. What a tangled mess of data! Thanks for all the info/insights! To my original question, is it odd that I got a 320 motherboard with a 240 battery from ninebot USA? I’m trying to understand if a 240 and 320 are the same with only a battery difference (which would explain my observation)
  5. I posted up my experience in the main mini pro forum, but I installed the more4mini swallowbot board yesterday and have been very pleased so far (only about 1 mile driven). I’m not sure whether I just modified a 320 or 240 model (the battery was labeled n3m240 but once I removed it, I saw a n3m320 serial number/info inside the device). My post contains additional observations about the install process.
  6. Thanks! That is very useful (and readable). I think that somewhat conflicts with the Xiaomi link I posted, so I’m not sure which source is authoritative.
  7. Having trouble uploading from my phone, but here is a link (serial number redacted) of the second device’s innards after the battery is removed:
  8. I just posted in this forum, but I purchased the more4mini board with swallowbot and can confirm that it increased my top speed and removed tilt back. My post had more details and observations about the installation process.
  9. My second device (that came with the 240 battery) had a label on the inside that said it was a 320. I’m curious if this is unusual or the status quo...
  10. I got a chance to drive a mile or so yesterday after posting. I didn’t experience any tilt back during my ride as I didn’t find myself hitting the new top speed. Instead, I was able to drive a bit faster than I previously would without the constant interruption of beeps and tilt back. It’s too early to declare victory, but it feels like this has addressed my primary gripe about my mini pro.
  11. https://files.xiaomi-mi.com/files/Ninebot_Mini/Ninebot_Mini_Instr-EN.pdf i believe this listed 350w
  12. I ordered one of the m4m swallowbot boards and installed it today. I have a standard wheels/etc. After installation, it looks like I could hit 14mph. I only had a chance to ride it a few minutes and will report back on this thread after I get a chance to really drive it around. Installation took me longer than I had hoped, but was ultimately pretty reasonable. Technically speaking, it is similar to swapping out a motherboard on a computer. The devices are remarkably well engineered and it was pretty easy to put Humpty Dumpty back together again. The most difficult aspects were trying to squeeze some of the small connectors that are on the underside of the motherboard while you pull them out (probably having a tool like the one on the instructional videos would have made it easier ... I used needle nose pliers). I had a hard time re-seating the motherboard as mine had some hardened white stuff (resin?) that made a nice tight fit at the end of the day but meant I couldn't drop it straight down. If you are going to do this, watch both the short video and the much longer video (you can skip the part where he is driving around). I'm glad I watched it before attempting the installation. One of the steps is pulling 6 ~banana plugs (not sure if that is the correct technical term). In the videos, you just pull them. Mine were shrink wrapped, so I had to use some pointy/smaller scissors to remove the shrink wrap. One thing not mentioned in the short video that was mentioned in the long video is that when you turn it on after all is said and done, it basically drives in a circle until you power it off and power it on again. This would have freaked me out if I wasn't prepared for it so I turned it on while upside down the first time. As mentioned above, all I've done is just drive up and down the block a few times to test the speed. I'll report more on the general ride once I've driven it some more.
  13. I cracked open my n3m240 today to install a swallowbot motherboard. On the inside, the there was a serial number and label for a n3m320. The battery says n3m240. Is it possible I received a n3m320 with 4300mah battery (in other words -- a bit of a frankenstein)? It explicitly listed 400w/motor on the tag and I believe the n3m240s are 350w.
  14. Thanks for the info! You wrote: "They come out of the same factory, the same base, the same chassis, the same materials, the same firmware, battery capacity and steering bar and hubcaps are the only differences.(weight too)" According to the specs I've found, it looks like there is also difference in the power of the motor as well (350W vs 400W per wheel). Good point re: the motherboard swapping. I'm getting a swallowbot board from More4Mini and should be more comfortable swapping hardware around between the devices soon.
