Assembly tutorial

A- Software installation

It’s better to start with software installation and modification, because after assembly memory card is not easily accessible (you need to re-open the casing to access).

Please check on internet for OS installation, there is plenty of good videos/tutorial on youtube/google. If you use retropie you need to make a little modification :

I prefer to let you edit config.txt because if version of retropie change then maybe config.txt will not be up to date anymore.

Open the SD in your computer. Open the file config.txt . You can edit the file with notepad++ freeware. With normal notepad you might make errors.

  •  At the end of that file, add this line:

dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4  

  • Modify these lines to adapt to the display:

# uncomment the following to adjust overscan. Use positive numbers if console # goes off screen, and negative if there is too much border  

overscan_left=-6 
overscan_right=-6 
overscan_top=-15 
overscan_bottom=-15

# uncomment to force a console size. By default it will be display’s size minus # overscan.  

framebuffer_width=320  

framebuffer_height=240

  • Also you can follow the following to increase font size, because it’s hard to read with basic setting :

B – Hardware assembly

IMPORTANT :

  1. Before anything, please make sure you are not charged with static electricity when opening raspiboy kit because you can damage it. Even break it with electrostatic charge. To make sure you are not charged you can touch any grounded metal : the water tapes of your kitchen or ground pin of a power socket. Click HERE to read more
  2. Please be very careful when placing the raspberry pi zero. Because if you put it the wrong side you will damage/break it and the memory card.When placed in the casing you should see the back of the raspberry pi zero. You should see the face without the components. And the SD card should be on top.Please be careful about that.
  3. Be carefull not to break the L/R wires (and others soldered wires) as they can break if you move them too much in all directions. Be gentle with them! See here a L button with broken wire: 
  4. Do NOT use raspberry pi zero W as it seem that it induced a lot of defects on the 8BCraft PCB, resulting in non-working screen (black LCD not waking up). I think the wifi interferences can corrupted permanantly the LCD driving software. This software is pre-installed by us on a flash IC that is soldered on the PCB. Flashing the software (.hex file) require specific hardware tools so you won’t be able to repair it.

C – User manual / important notes : 

1 – To turn ON the Raspiboy use the switch. To turn off the Raspiboy first shutdown from software, then when LCD goes crazy use the switch.

2 – Raspiboy should not be used while charging. It might cause failure of the PCB. Also when plugging/unplugging power cable into a turned ON Raspiboy it might crash the unit.

3 – To switch to HDMI you need to turn OFF the Raspiboy, plug the HDMI cable, turn ON the unit. Same if you want to switch back to composite

 

D – For Extra USB :

1. Remove thin plastic with cutter or shard blade

2. Solder the extra USB to the 8BCraft PCB at the back. Color code is :

Black : GND

Green : D+

White : D-

Red : 5V

3. Use small piece of double face tape from battery to stick the USB to the casing where you chopped the thin plastic part.
