What your phone will look like soon!
Useful skills for assembling the Ringo:
Basic soldering experience (just a bit of practice beforehand)
Ability to recognize basic electronic components
If you aren’t sure of your skills, don’t worry. By following these instructions carefully, you’ll be sure to catch up in no time.
What You’ll Learn With the Ringo
Ringo’s main goal is to educate and motivate you to learn something new or brush the skills you already have.
In the process of assembly, you’ll learn:
How to solder.
Name basic electronic components and their function.
How to connect electronic components and why.
What micro controllers are and some basics of digital electronics
If you go further and follow our coding and hacking guides, you’ll learn:
How to program a mictocontroller in C/C++
How a simple video game works
How to interface a microcontroller with external peripherals

3. Brain board & SD card
This board is what makes your phone do smart stuff such as display text on the screen or read the SD card.
It contains the main microcontroller (the big silver square thing), as well as an SD card slot and an RTC chip.
“RTC” stands for “real-time clock” and it’s the main timekeeping chip on the Ringo. Basically, that’s a chip that counts time and triggers alarms - every microwave has it nowadays.
It also contains the power management and shutdown circuitry that can turn the whole device ON/OFF, charge the battery, measure the battery voltage, etc.The on-board micro USB port is used for both charging and programming the device.
A regular Micro SD card is Ringo’s main storage device and is used for storing media, apps, games, settings and more.
The SD card comes included in every kit and is inserted in your Brain board.

4. Display board
This board’s main component is, of course, its display.
LCD stands for liquid crystal display and when applying a current to the crystal layer inside the display, it changes which color that part of the screen will be.
It features a 160×128 pixels display with 8-bit color depth at a 1.8” screen size.
The display should provide you with plenty of possibilities to make some amazing pixel art in your games and apps.
NOTE: 8-bit color is a method of storing image information such that each pixel is represented by one 8-bit byte.
There is a palette map with three colors: red, green and blue (RGB), where each color is represented by a value between 0 and 255, thus creating 16,777,216 color combinations.

5. Sound board
The Sound board contains a DAC chip, a microphone and a headphone jack that need to be soldered onto the board.
DAC stands for digital to analog converter and it converts the digital data (1/0) to an analog signal (a.k.a. music and sound effects that are played out on the speaker).
The board incorporates a DAC chip with a 3.4W amplifier in a single package!

6. Analog joystick
This joystick is the phone’s main navigational input, whether it’s scrolling through a text message, flying around in a game or navigating down a menu.
The joystick has two axis and cannot be clicked.
7. Micro USB cable

8. SD card reader
In order to make your life a bit easier, we have also included a handy Micro SD card reader.
Just insert the included Micro SD card in and then you can put all your favorite songs and photos, as well as Ringo-compatible games (.BIN files) onto it.

9. Li-Po battery

10. Network board
Without this module, you can’t make calls, send messages, or get the correct time from the cellular network.
Basically, this board has a secondary microcomputer that handles everything related to mobile phone network communication.
These chips come pre-certified and pre-approved and they’re used in other products that need to communicate via cellular network.
Every network module has a unique IMEI (International Mobile Equipment Identity) assigned to it and written on its front side.
Depending on which Ringo version you ordered and which version you’re located in, your network module may differ.
The 2G standard version comes with a SIM800C module (the black board), and the 4G version comes with a more powerful SIM7600 module (the green board).

B) 16x small black pushbutton
C) 3x machined header pin stick
There are two types of buttons on the Ringo: the smaller ones that are used on the numerical keypad for entering phone numbers and the bigger buttons used for navigating through menus.
They’re the essential input sources for navigating menus, playing games and using apps.
The pin headers come in long sticks and are used to connect all the different modules to the Main board.
They will need to be cut to appropriate size and soldered onto the other boards.
