As stated, you need the V3 electronics that install into the back of the A&D scale, a connection cable for the IP Trickler, and a new power supply (I don’t think the one that comes with the scale supplies enough power to run the trickler). All three of these items are available from Adam on the AutoTrickler website for a total of about $100.00.
If you’re not ready to drop the entire load of cash at once, I think it’s a good idea to start with the A&D scale and an inexpensive manual powder measure and trickler. It will get you going and you will be able to obtain extremely accurate charge weights with a scale that doesn’t drive you crazy drifting all the time. Later, when you’re ready to spend more for upgrades you’ll already have the scale you need for that.
I went from a beam scale and manual thrower and trickler (for decades) to the A&D scale (still manual thrower and trickler), to now using the A&D with manual thrower and the IP Trickler. Each step was a quantum leap forward in ease and convenience. I am currently waiting on IP to release their complete system so I can upgrade to auto-throw as well (I will just be purchasing the auto-thrower upgrade kit, as I already have everything else.
Manual trickler setup I used (and no, the trickler sitting there on the lid doesn’t affect the scale because the windscreen and lid don’t contact the platen of the scale, they contact the scale housing):
