    Unknown control module on electric ATV

    Trying to identify this component board, but cannot find any information about it

    Hope to find answers here on the forum. Or if anyone can show me in the right direction 😁

      Re: Unknown control module on electric ATV

      The little board is an RF remote control receiver, ASK or OOK. It receives data from the wireless remote and sends serial data to the SC2272 remote control decoder IC.

      The red trimmer cap is for tuning the receiver to match the remote's transmit frequency. You can troubleshoot by looking for signal at the little board's DATA pin. There should be the usual noise and a burst of data when the remote button is pressed.

          ALPS Electric BT/WLAN Combo Module Experiment
          by r3vsEngIT
          i have a 2017 volvo that i upgraded the stereo in but the week link now is the SBC codec the head unit uses to transmit audio. i took the unit apart and we have a UGKZ2 combo module with a CSR8311 bt chip. after some research it is my understanding that ALPS made another combo module that used the CSR8350 chip. this chip is capable of aptx. https://vehicle-electronics.biz/cont...s-alps-modules

          my question is, would it be possible to swap out this UGX module as plug n play? what about replacing the CSR chip itself? any idea where to get either?

          Jeep Drive-train control module repair
          by unimatrix93
          Dear forum,

          My father's Jeep has this annoying rattling sound which is caused by the Drive train module as it constantly moving a solenoid.

          It comes and goes as the temperature changes. For example, when you cold start the vehicle from a long parking time, it starts loudly (especially on winter) then it goes silent as the vehicle's temperature rises.

          So I took the DTCM apart and found this damaged ceramic cap, which I should replace:


          Now the problem is that I couldn't find the schematic for this module, nor I could identify the circuit...

          Replacing the WiFi module on a vacuum cleaner iROBOT i7
          by AlexVG
          Hi,
          I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.

          I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
          (This board does not respond, only the LEDs light up in a circle.
          The liquid damage is catastrophic and restoration is impractical).
          (I bought this board to get the WiFi module and camera).

          The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

          If...

          TOSHIBA DLP 52HM95 How to reset timer module on bulb
          by repair-it
          I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?

          Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently...
