second version; this time I’m using the right connectors!

0-24v PWM to adjustable DC voltage converter with full optoisolation

Version 2 of this PCB is available here.

My version of a 2x3, 1.27mm pitch POGO pin adapter. Inspired by PogoProg Model D that I’ve used, but is no longer in stock.

Materials

• 0.68mm diameter POGO pins; P50-E2 or P50-B1
• 2.54mm pitch 2x3 header; male, right angle or male 2x3 socket

Assembly Tips

• Place the PCB on top of something with the POGO pin side hanging over the edge.
• Insert POGO pins, using the height of the object(s) holding the PCB up to set the high of the POGO pins.
• May help to insert and solder two pins at a time.
• Use lots of flux to help the solder flow.
• Excess solder can be removed with a solder sucker or by wicking small amounts of solder onto a clean iron tip, cleaning the tip, then repeating several times.
• Wash POGO pins thoroughly with Isopropyl Alcohol (IPA) after assembly to remove any flux inside the pins that might cause them to become stiff later on.

NOTE: all links are unaffiliated and provided as an example of what is needed. you do not need to buy the exact items linked to in order to assemble this board. cheaper/better alternatives may be available elsewhere.

Just a simple board which allows you to extend your GBA’s cartridge slot to another PCB by using a 32 pin FFC. You could have it work with Gameboy games if you apply some glue to the GBA cart to trigger GB mode.

Should be ordered as 0.8mm
