IO Board Assembly
NOTES¶
This page is for reference only. It may not be up to date. It may not include the BOM for latest PCB version. You need to check the schematic and required components yourself!
The following section will walk you through the steps of creating your own Mister IO Board. It describes where to order all necessary parts like PCB and components. It will also give you an overview on the equipment you need and show you how to assemble the board.
Important Note:¶
I/O board has an option to provide either +5V or +3.3V through VGA PIN9. It’s supposed to be used in some handmade active VGA adapters/converters. Some cables and displays have PIN9 grounded which will make short circuit if P8(VGA PWR) has jumper! It’s advised not to solder P8 at all, so PIN9 won’t have a power and it will be safe to connect any cable/display. Use P8 only when you are absolutely sure you need the power on PIN9.

Convenient order of manual soldering:¶
1) resistors, capacitors, diodes, transistor 2) SD socket 3) buttons 4) LEDs 5) connectors, jumpers, switch
P7, P9 Notes¶
1) Cut connector to 8 pins 2) Remove 3rd pin (use for P9) 3) Insert pins through IO board into DE10-Nano 4) Solder from top 5) Trim pins flush
