Female JST connector 

This connector is pre-

soldered to MAKERbuino’s

 PCB and is used for connecting the Li-Po 

battery to the circuit. 
These white JST connectors are different from regular connectors in a way that 

they are anti-

reverse

. In other words, you cannot swap polarity while connecting the battery. This is 

important because reverse p

olarity can damage MAKERbuino’s charging circuit.

 

   

 
 
 

Important: the “sandwich”

 

Some of the above components (PCB, casing, some nuts and bolts, female battery 
connector, Li-Po battery) might come packed in this sandwich-like form displayed on 
the picture. 

The reason for sending you those components like that is a regulation that doesn’t 

allow us to send the Li-Po batteries via airmail if they are not embedded in some kind 

of a “device”.

 

Before assembling the MAKERbuino, you will have to unscrew the sandwich and 
release the PCB so that you can solder the components on it. 

Electronics 101: never solder or modify a device that is 

“alive”.

 In other words, 

always unplug the battery or some other power supply from the 

device’s

 PCB, 

otherwise, you might make a short circuit with your soldering iron or screwdriver 
and damage the electronic components.

 

 

 
RS232 Serial UART adapter & the corresponding 6 pin 
cable 

This red Serial adapter board is connected to MAKERbuino’s serial port (top left 

black female angle connector). 
It allows you to program your MAKERbuino directly from your computer and send 
all sorts of useful data from the computer to the MAKERbuino and vice versa. 

The board is connected to the MAKERbuino with a 6-pin rainbow female to male 
cable.

 

You 

won’t

 need these components in the basic assembly so you can put theaside 

for now. 

 

 

SD card (m 
SD adapter) 

  

The included SD card is used for storing games, programs and other useful data on it (game 
graphics, music etc.). 
Thanks to this card, you can load multiple games on your MAKERbuino. 

It comes preloaded with lots of fun games downloaded from 

the games gallery

 so that you can 

try it out right after you assemble it.

 

You might be wondering why the card’s capacity is only 128 MB. This is an 8

-bit gameboy-like 

gaming device and programs and games for it are approximately 30 kB. Thus,128 MB of space 
will be more than sufficient for storing plenty of games, programs and useful info. 

 

 
Speaker 

  

This neat little speaker fits at the back side of the device, it has a special place in the back 
of the casing. 

It plays a crucial role in producing all the beeps, boops and crazy chiptunes 

you’ll

 

compose in your very own games.

 

Power: 0.5W, 

Impedance: 8Ω,

 Body dimensions: Ø28 x 4.7mm
