KKC – Kiss Keychain Configurator [ENGLISH]

The Kiss Keychain Configurator (KKC) is a small device with a 0.96 “ OLED display and micro-USB socket, which can be used to configure all common KISS FCs. Alexander Fedorov (a former KISS developer) started this project a few months ago. The goal is to create a simple tool that can replace the laptop on the airfield and also serves as a backup memory.

 


When Alexander called me and asked if I would like to test the KKC, of course I did not say no! I like to support him, because I really appreciate him for his work on the KISS firmware! =) Thank you Alexander!

  • KISS FC V1 powers KKC via USB
  • 2-5S input
  • charge 5V USB devices from LiPo (500mah)
  • LiPo voltage tester
  • connects via OTG cable
  • Gyro & Spectrum graphs
  • USB to Serial bridge (for WiFi and Bluetooth – not supported yet)
  • ready for Betaflight FCs (not supported yet)

Availability

#itsreadywhenitsready

In just two months Alexander has created a finished prototype and put hours of work into the firmware. The beta testers now diligently test the firmware and report bugs and improvements. Currently, a shop is set up and the first batch made in China.

The KKC is expected to be on sale in these stores.

Cable

For reasons of space, a normal USB socket was omitted. For the connection with the KISS FC an OTG cable is needed. I am using the following OTG cable (China). There, the „OTG“ part is already included in the cable. Alternatively, you can of course use a conventional USB cable and an OTG adapter.

ANZEIGE:

Menus and navigation

For navigation through the menus, a 5-way joystick is installed. Next to left, right, up and down you can also press down the joystick, which acts as confirmation. If you want to scroll, you have to hold the key up / down for at least 2 seconds. You can get back by pressing long to the left.
The rest of the menu is intuitive, so I will not go into it.

FC Setup

Here you can configure the complete FC. In addition to Pids, Rates, VTX, Filters and Modes you will find all the settings that are also available in the Standalone GUI.

Backup Restore

A long press on the joystick (in the middle) will bring you to a submenu where you can save the settings you have made („Save„). If you want to read the current settings from the FC, you have to press „Load„.

In addition, the KKC offers storage slots in which complete configurations can be stored.
Up to 10 slots are available. You can also name the individual slots.
For example, you can backup your Copter or create a basic configuration, which can be copied in seconds to a new FC.

ESC Setup

If you want to operate your KISS ESCs in 3D mode or change the direction of rotation, you can do this with just a few clicks.

Model Info

In the menu „Model Info“ you will get every information about your kiss setup

You will receive the current firmware of the FC / ESCs and in addition all telemetry data of the ESCs will be displayed.

RX & Motors

Here you have the opportunity to view all RX channels. You can also see the motor speeds and the arming status. I suggested Alexander to create a second page, on which the channels are also to be seen as numbers, because then you can adjust the channels much better with subtrim (1000us / 1500us / 2000us). He will implement it soon in the next version.

Motor Test

About the engine test, you can test one or more engines. Just select with „Yes“ the engines that should run.

Please always test without propeller!

Gyro & Spectrum graphs

Once the motor test is started, you also have access to a Gyro & Spectrum graphs.

This appears immediately after you throttle up. It is purely a motor test, the PID controller is not active. If you also want to turn on the PID controller, you must first arm the quad.

Tool Setup

Via the tool Setup you can switch on the „Serial Bridge“. There are built UART pins where you can connect WiFi or Bluetooth devices in the future.

Tool Info

In menu „Tool Info“ you can see which firmware is installed on the KKC. Among other things, you can also find the battery voltage and cell number of the connected battery.

Charge Mode

The KKC can also be used as a 5V USB charger. The charging current is however limited to 0.5A.
If the voltage drops below 3.4V per cell, the LED will start flashing quickly and „replace LiPo“ will appear.

KKC Firmware Update

A firmware update is extremely easy and you do not need any drivers. It emulates a USB drive on which one must copy the firmware.

Step 1: keep the joystick pressed to the right
Step 2: Plug the KKC into a computer via USB cable (Windows / Mac)
Step 3: A USB drive named „KISS_KC“ will appear
Step 4: release the joystick
Step 5: Download the current firmware and copy it to the USB drive via drag and drop (or copy / paste)
Step 6: Wait until the KKC has flashed itself and reboots itself. Finished!

Betaflight?

Why not! The KKC is hardware technically able to configure also Betaflight FCs. Alexander has suggested that this may come in the future via firmware update. For the time being, but first it remains for KISS hardware.

Case

I have already developed a housing for the prototype. However, since the final version has a few adjustments, I stopped the development for now. Maybe a case will not be necessary, because there is a metal protection for the display is soldered. We’ll see!

  

 

Suggestions for improvement and ideas?

Do you have an idea what should not be missing in the Kiss Keychain Configurator? Then let us know in the comments! =)
