  1. Let's see what the Razer Kishi brings to the smartphone gaming ... game. Standard A-B-X-Y buttons, two clickable analog thumbsticks, one 8-way D-pad, plus a shoulder button and a trigger button on each side) Direct connectivity to your phone via USB-C or Lightning connector (depending on which model you buy)
    • Let's see what the Razer Kishi brings to the smartphone gaming ... game.

    • Standard A-B-X-Y buttons, two clickable analog thumbsticks, one 8-way D-pad, plus a shoulder button and a trigger button on each side)

    • Direct connectivity to your phone via USB-C or Lightning connector (depending on which model you buy)

    • This enables charging while gaming via the passthrough USB-C port on the bottom of the Kishi

    • No internal battery, no Bluetooth, and no headphone jack

    • Compatible with Android 8 Oreo/iOS 9 or higher, supporting device dimensions of 145.3–163.7mm (H), 68.2–78.1mm (W), and 7.0–8.8mm (D)

  2. Two slide locks on the back of the Kishi secure both halves of the controller, keeping it compact when there's no phone attached. Pulling outward on both inserts releases the clip, so you can extend both sides of the Razer Kishi until your phone fits in between. You may have to remove your phone's case. That's what we call gaming on the edge.

    • Game time started—we blast off ten Tri-point screws from the rear side. Thankfully we came equipped with 64 bits of Mako Driver Kit goodness. We're leveling up already!

    • Beneath the back cover, we find two Steam-ish booby-trap interconnect cables—each one snaking off to a separate circuit board.

  3. Instead of the tricky Tri-points found in other portable gaming options, we find regular Phillips #0 screws inside of the handles. Normally each new level gets more challenging, but here it seems Razer gave us a break. Or is it just a distracting side quest? Regardless, we're happy to go on a Phillips fetch quest.

    • There's no boss battle here yet—just a couple boards, which we quickly extract.

  4. The right board contains the following bijous: Fresco Logic FL7102, USB3.1 Type-C PD3.0 Controller
    • The right board contains the following bijous:

    • Fresco Logic FL7102, USB3.1 Type-C PD3.0 Controller

    • Soldered-on USB Type-C charging port

    • Soldered-on joystick controller (hello Oculus Touch and Xbox One S)

    • Plug-in phone connector (in this model USB-C)

    • Soldered-on breakout board for one of the shoulder buttons

    • "Forward" button

    • Indicator LED

  5. On the back of the board we discover: ARM®32-bit Cortex®-M0 CPU
    • On the back of the board we discover:

    • ARM®32-bit Cortex®-M0 CPU

    • Broadcom (formerly SiByte) 4407 DA9N1S microprocessor

    • A breakout board for the second shoulder trigger, which is attached separately and is therefore easier to repair.

    • This one seems to use some sort of rotary knob offering not only an on/off status but a gradual push depth of the shoulder trigger.

  6. Extracting the left circuit board reveals: Another joystick, which is also soldered in place Four golden contacts for the D-pad (similar to the ones on the first circuit board)
    • Extracting the left circuit board reveals:

    • "Back" button

    • "Home" button

    • Gamevice has rather unmistakably left its mark here—just in case you wondered with whom Razer partnered up for this controller.

  7. What remains is the telescoping slider mechanism that supports your phone when attached to the Kishi. It includes a folding rubber cushion, which attaches to the back cover with small springs. That's what saves you from worrying about scratches on the back of your phone while gaming. As you may have noticed, all external faces of the controller can be separated from the electrical components, which will make individual paint jobs a breeze!

    • Quest complete! That's one more adventure mastered. Is it time to start working on a speed run? Let's recap what we've learned:

    • Overall easy disassembly (with the right drivers). Some danger of losing small components and buttons. No ability to save your progress, so finish your homework and take out the trash before you start.

    • One final question: Can it post a high score?

  9. Considerazioni Finali
    • No adhesive was used and components are attached with screws.
    • The controller's relatively modular construction means replacing most components will be a simple task.
    • One of the most strained parts—the phone connector—is plug-in and easy to replace.
    • We always say screw before glue. But using two different types of screws—one of them being Tri-point—is unnecessary and a bit annoying.
    • The most likely-to-fail components—both joysticks—are soldered directly onto the circuit boards, as is the passthrough USB-C charging port.

Nice teardown! Looks like a DIY Nintendo Switch with the phone on, even down to the joystick/main button locations.

Ethan Zuo - Replica

Very useful. I wonder if there's any unused traces on the ribbon cable: thinking of adding stereo speakers using a small Bluetooth module (though it seems rather packed).

sam_hardema - Replica

That’d be nice tinkering. Please share if you find anything.

Ubon BT40 kit

I’m still wondering why Razer didn’t include support for USB-C headphones. Looking at the internals makes me wonder if it was more work to make it charge-only.

Lanford Gabriel Murillo - Replica

I wonder if those analog stick caps can be swapped for the ones from an actual Xbox One controller? I bet that would be an upgrade.

Josh Brackin - Replica

Please share if you tried that swap. I bet others wonder about that too.

Tobias Isakeit -

where can i buy spare parts for the pad?

Adrian - Replica

Unfortunately we don’t have spare parts for that controller. Hope you’ll get lucky on the interwebs.

My kishi failed on me after 4 months. I can assess it was the passthru usb-c charging that caused it's demise. I noticed it was hot and unplugged it not being worried. Hours later I reconnected it with no input to be found. I'll probably never repair it but I enjoyed this teardown none the less…

Whats the white stuff on the spring of the trigger buttons?

Robert Torres - Replica

That white stuff is just some lubricant to make the triggers go swoooosh ;) (and not get jammed on its plastic guide rail)

Tobias Isakeit -

My communication flex has failed, where can I get a replacement? Or what are the characteristics of the flex?

NintenDub - Replica

well, I found the ideal flex for this game on AliExpress, it is 14 pins, with a difference of 0.5 millimeters between them and the direction of advance.

Whats the dimensions of the analog? I wanna replace it with 3D flat analog, i really dont like the sticks ……

Cameei Webb - Replica

Hi @Cameei, we think it is the ThumbPointer stick with serial number RKJXV. Here is the matching data sheet: https://www.mouser.de/datasheet/2/15/RKJ.... Have fun with the replacement!

Do you happen to know which pins are broken out on phone connector?
