(Vers 1.1) Quad opto-coupler (opto-isolator) breakout with line status LEDs. See http://sheepdogguides.com/elec/pcb/PCB274-quad-opto-coupler.htm

ORDER .8 MM!!! This is an adapter to translate star ocean or using an sdd1 snes cart. Uses an m27c322 S1 chip which is smaller and a better fit than the huge f1. Use is same as my sa1 adapter. program the chip then place in adapter and flush cut legs then solder adapter to board making sure all connections are good then solder ic in. square notch is pin one. Program the chip with my adapter for the gq 4x also on this site to download. Get the chips from barum electronics they have plenty

This PCB board is 17mm in diameter, it has a four P-Channel AO3401A channel mosfets that is capable of tolerating 30V 4A each. It should be fairly simple to solder, even that it is surface mounted. It does not conduct any electricity if subjected to the wrong polarity. It has two solder pads,the one on the DC protected side can be soldered to the top of your existing drivers spring. There is also two DC- or ground connections, I suggest a AVG 15 (1.45 mm diameter ) flexible wire for this usage. The + IN unprotected side goes to the batteries. DC OUT to the driver spring, as this is the protected side.

BOM: four P-Channel AO3401A

This board is a current source for an X-Ray tube filament. It can provide between 1.5A and 2.5A using the IRF530 to regulate 12V. The current limit is adjustable using the DS3502 Digital Potentiometer.

The board also features 12V out and 5V out for powering other devices. (12V power limited to input power supply, 5V limited to <1.5A)

This PCB board is 31mm in diameter, it has a single P-Channel IRLR9343TRPBF mosfet that is capable of tolerating 55V 20A. It should be fairly simple to solder, even that it is surface mounted. It does not conduct any electricity if subjected to the wrong polarity. It has two 13mm solder pads,the one on the DC protected side can be soldered to the top of your existing drivers spring. There is also a DC- or ground connection, I suggest a AVG 15 (1.45 mm diameter ) flexible wire for this usage. The DC+ unprotected side goes to the batteries.

BOM: one P-Channel IRLR9343TRPBF MOSFET.
