Since discovering a fault with the original displays, we’ve been extensively testing solutions, the result of which has been switching to a new display, a tweak of components, and completely redesigned software (the protocol for the new display is quite different). New PCBs are en route, and we hope to have units back on sale in the next few weeks.
As we’ve mentioned above, testing takes a looooooooong time, unfortunately. This is part of the reason that we failed to spot the problem initially, because it only manifested after the units had been running continuously for several days.
We’re fairly happy now though that the solution we have is a robust one. The plan is to release a small number of the new units initially to get feedback on them, then push out the remainder of the new batch after that.
Apologies again for the time that this has taken. We really love Inky pHAT and were delighted with the response when we released it, so you can imagine how disappointed we were when we had to take it off sale.
We’ll endeavour to keep this thread updated with information as and when we have it. :-)
