If I'm ordering boards for myself, do you think hasl is good enough or do I need to spring for the enig? Also, does the pad on u1 need to be connected or can I cheat by soldering around the edges? Or is it one of the qfn chips that don't have accessible edges?

It looks like the PSVSD is out of stock on SphereSolid, is there an ETA on a restock? I see there is an available listing on AliExpress but don't want to roll the dice if I can help it.

first i have psvsd (copy from ALI) v 2.1
i grounded shield like in v 2.1.1
when Vita is turned OFF (not sleeping) mode, its slowly discharging the battery - 1% in 2hrs
if i etract PSVSD module, The battery is not discharged even by one percent for the whole day

nobody have this problem?
i think copy made by official manual, and If this problem is present here, then it is in the original

My PSVSD v2.1 (official one sold by you, not the third party) discharges Vita battery even if the system is completely turned off (power button held for a few seconds and selecting turn off option). It's not much, since it takes several days to drain 10% of the battery, but if you leave your system long enough, it will discharge the device to the point to not be able to even turn it on again (that was the case when I first noticed the issue after not using the Vita for about a month - all battery charge has been drained even though the Vita remained completely turned off).

I've noticed similar issue reported before: #9 but I didn't managed to fix it. I've tried following things to make sure that it's PSVSD v2.1 that is causing the discharge:

• leaving PS Vita turned off for about a week without PSVSD - no battery discharge whatsoever
• leaving PS Vita turned off for about week with PSVSD - several % drained,
• as above but after unplugging and connecting back the battery - same problem with discharge
• as above but also after removing official memory card (as was suggested in the linked issue) - same problem with discharge
• after removing PSVSD again, I’ve inserted 3G module back and the problem is no longer present (no battery discharge)

Hello yifanlu,

I've produced a batch of PSVSD, and I am currently selling them at the suggested price. I wanted to thank you for your time and efforts. I intend on keeping it at a low cost. Please check out my website, where they're available. If you'd like one of mine, please don't hesitate to ask. Thanks again!

I am new to ordering PCB's or even assembling them. I want to upgrade my PSVita with the Psvsd Board but sadly it's sold out on Indiegogo :(
I asked you already on Twitter where I can order the Board assembled and you told me to look on PCBWay but sadly I have no clue what to fill in or how to produce the Board. Can you give me a Screennshot of what you filled in ? / share the Project via Link if possible ? (example)

Save a resistor, and it'll actually do the reset off when the 3.3V goes up...

(Not a big issue, but github doesnt have that good messaging... feel free to close.)

Microchip provided some good feedback on the design. However, in the interest of time and costs, I think the current design is "good enough" for the first run of cards. I think they will work 99.9% of the time in 99.9% of use cases. Incorporating these comments will only make it better.

The following will be done:

• Select crystal with drive level between 300uW and 500uW with 350ppm accuracy
• Recalculate C3 & C4, the crystal capacitors
• Verify C7,C8 are low ESR
• Improve POR circuit
