[FRAM71B] 3rd Batch Announcement
after struggling the last two years to get my new flat up and running, i'm finally able to process a 3rd batch of FRAM71B. conponent acquisition is finally done, and i'm currently negotiating the production run with an EMS.

the 3rd batch of FRAM71B will have exactly the same functionality as the previous one. there will be an ample amount available, so no need to rush and try to pre-order. pricing will be same as before, as i was able to cut the cost down to compensate for the (insane) price increase of the FRAM memory.

however, the amount of 512kB extenders will be pretty much limited because of the extra manual labour envolved to assemble the connectors. hence, i've decided to release all design files for the extender (pcb data plus BOM and assembly instructions) to the public, i.e., here in the forum. pcb data will be in a zipped format that allow direct order at JLCPCB. i hope that this will enable everybody, who is not suffering the "2 left hands" syndrome, to assemble a 512kB extender to update his/her previously acquired FRAM71B.

due to the current covid situation, it is not possible to give a definite timeline, but i'm pretty confident that the production run will commence no later than Q1 2021.
as pointed out already, there is no need to rush right now. in fact, i will also be contacting all folks that approached me via email during the last two years. i will be updating the process in this thread in the following months, so stay tuned for further info.

Update 2020-12-01:
updated FRAM71B-EXT_DIY.zip to V03 to clarify required options for ordering the pcb. no change to included gerber files.

Update 2020-11-22:
added FRAM71B-EXT_DIY.zip for all FRAM71B owners who want to roll their own 512 KB memory extender. in the zip-file, find all necessary board-files with JLCPCB-conforming naming convention, schematics, BOM and photos of assembled unit.


Attached File(s)
.zip  FRAM71B-EXT_DIY_V03.zip (Size: 820.78 KB / Downloads: 13)

Assuming you'll mention it in this thread once they become available, so keeping an eye out!

There are only 10 types of people in this world. Those who understand binary and those who don't.

Great news! I am very late to the 71B Game and I thought I would never have the opportunity to have one of these!

Hi Hans,

Great to hear you are fine. Glad to read you are preparing a next batch of the FRAM. I‘m interested in a FRAM with extender like I wrote in one of my replies. No hurry ;-)
best regards - Erwin

It's quite easy if the connectors are installed as done on the left, below.
