mozzwald Posted March 5, 2021 Share Posted March 5, 2021 There is a new DIY through hole FujiNet hardware design that uses the espressif devkitc-ve board. It's basically a shield for the devkit board with all the needed bits for FujiNet. I'm happy to finally see someone else release hardware based on the completely open FujiNet design. https://github.com/djtersteegc/fujinet-devkit-shield 7 Quote Link to comment Share on other sites More sharing options...
Fierodoug5 Posted March 5, 2021 Share Posted March 5, 2021 Very cool. Will most definitely building one of these up. Thanks for the link 1 Quote Link to comment Share on other sites More sharing options...
+LarryL Posted March 8, 2021 Share Posted March 8, 2021 excellent! I've ordered a few PCB in China and will check this out time to give FujiNet a start... 1 Quote Link to comment Share on other sites More sharing options...
+ZuluGula Posted March 8, 2021 Share Posted March 8, 2021 I don't know how to use GitHub, so can someone suggest to the creator to add footprint for SIO connector? Preferably a DB15/SIO combo, same like one used in 1088XEL pcb for example. Since @Sikor is selling new, high quality, injection molded SIO connectors, some people could chose to build this device with SIO socket and use original Atari SIO cable. This would eliminate the need for DB15 adaptor cable. 1 Quote Link to comment Share on other sites More sharing options...
Sikor Posted March 8, 2021 Share Posted March 8, 2021 Look here: Maybe better way will be made it for this pinouts? My Super SIO Splitter will be ready probably on the end of this year. Maybe in few weeks I'll get some PCB's boards for new-device designers. Quote Link to comment Share on other sites More sharing options...
hideehoo Posted March 8, 2021 Share Posted March 8, 2021 (edited) I'm the original creator. @Sikor, do you have a mechanical drawing for your new SIO jacks? Or if you have a KiCad footprint already, that would be even better. Edited March 8, 2021 by hideehoo 2 Quote Link to comment Share on other sites More sharing options...
hideehoo Posted March 9, 2021 Share Posted March 9, 2021 I grabbed the Eagle footprint from 1088XEL project and converted it to Kicad so if your jacks work on the 1088XEL (including the mechanical mounting holes) @Sikor, I'm good to go. This addition would also push the current board over 100mm in length (~105mm) so the $2/5 JLC type deals would be a few dollars more for small orders. But hey, you're spending the big money on an SIO jack now so you can afford that extra PCB cost. ? My current BOM (minus the PCB and ESP32) is right around a $1 when using all Aliexpress sourced parts bought in qty 10+ when built with a pin header connected cable. 2 Quote Link to comment Share on other sites More sharing options...

But, if you want - I'll have few Super SIO Splitter boards for new-device creators and I can send you one for test (probaby I got it for next 3-4 weeks, and yes, I have few prototype in home, but there are reserved). Send me PM. One more - my SIO socket are mechanical identical with Atari in PCB parts, Edited March 9, 2021 by Sikor more info Quote Link to comment Share on other sites More sharing options...

Is there anything under ESP32? You could move resistors over there. Or maybe you could move the switches in the same row with leds, put them between leds.

+mytek Posted March 9, 2021 Share Posted March 9, 2021 I noticed that in this THT version board, the BOM appears to spec out an 8GB device. Is there a 16MB version of that espressif devkit? Quote Link to comment Share on other sites More sharing options...

So if the 8GB board is used, what is the compromise, and does it affect what firmware gets programmed -or- the use of the FujiNet Flasher app?

You can use PlatformIO/VSCode to build and flash the 8MB board by using the 'fujinet-v1-8mb' board config option that was recently added. The wiki on github has instructions for setting up pio/vscode to build fujinet firmware. Currently, we aren't using the entire 16MB and that's why the 8MB variant still works. In the future as we add features the 8MB may become 'obsolete'. There is effectively no price difference b/w the 8MB and 16MB module so we went all the way 1 Quote Link to comment Share on other sites More sharing options...
hideehoo Posted March 9, 2021 Share Posted March 9, 2021 There are some 16MB devkit boards available like the LOLIN D32 Pro, but I wasn't overly impressed with the build quality and the wiring of the on-board MicroSD slot conflicts a bit with the current FujiNet GPIO selections (but that could be fixed in code with some #ifdef's). Big reason I didn't go that route was availability was sketchier and pricing worse (once you factor in the increased shipping costs from China) than the official devkit boards from Epressif which are widely available from multiple component suppliers. The #1 goal of this project from my perspective was to give users an easy and cheap way to build their own FujiNet device and expand the community of folks with access to the software stack. Below is the partition map differences between the 8MB and 16MB options. Much of the current 16MB model appears to be used for a secondary OTA update partition (app1). Only real difference is in app0 where you load the currently ~2MB compiled Fujinet code. spiffs is where things like the AUTORUN.TR file are stored, currently ~800KB used. Technically you can still run FujiNet even on a 4MB WROVER board, but as mozzwald states above, this could all change in the future. 8MB -- #nvs 36,864 to 57,344 : size 20,480 #otdata 57,344 to 65,536 : size 8,192 #app0 65,536 to 6,291,456 : size 6,225,920 #spiffs 6,291,456 to 8,388,608 : size 2,097,152 16MB -- #nvs 36,864 to 57,344 : size 20,480 #otdata 57,344 to 65,536 : size 8,192 #app0 65,536 to 6,356,992 : size 6,291,456 #app1 6,356,992 to 12,582,912 : size 6,291,456 #spiffs 12,582,912 to 14,680,064 : size 2,097,152 2 Quote Link to comment Share on other sites More sharing options...
manterola Posted March 9, 2021 Share Posted March 9, 2021 (edited) I also got surprised by that 8MB devkit. The good thing about the 8MB board is that it is widely available. However, I would have prefer the use of 16MB one like the "LOLIN D32 Pro" ~$19 in amazon and also available in Europe, which include sd card reader (probably using different pins than the Fujinet 1.x), but anyway... Maybe an opportunity to contribute with an additional version. Just my $0.02 Edited March 9, 2021 by manterola Quote Link to comment Share on other sites More sharing options...
hideehoo Posted March 9, 2021 Share Posted March 9, 2021 <shameless promotion> My extra boards from the first run are up on Tindie finally if you are in the US and want one shipped to your door for $5. https://www.tindie.com/products/tersteeg/fujinet-devkit-shield </shameless promotion> 4 Quote Link to comment Share on other sites More sharing options...

Just my $0.02 There's also the Lilygo TTGO T8 which looks like it might come in the correct 8MB PSRAM/16MB Flash combo these days (and is competitively prices), but conflicting info on all the AliExpress listing and even Lilygo's official site had me shying away from that option also. e.g. https://www.aliexpress.com/item/4001049652653.html It also have the same SD card wiring issue as the LOLIN board, which would require additional changes in the FujiNet code to work.

manterola Posted March 9, 2021 Share Posted March 9, 2021 Oh! I got that one but version 1.8... To make it work I needed to redefine pins , not only the Sd card pins, but also others that conflict with the Fujinet assignment. But it works (after redefinition of the spiffs partitions). The v1.8 does NOT include 16MB 3 Quote Link to comment Share on other sites More sharing options...

Fierodoug5 Posted April 14, 2021 Share Posted April 14, 2021 It is just a very simple case design, and you will have to adjust the buttons depending on the height of Tact switches you used, I moved the LED's to the case lid, But I added light pipes to the design so you can also use it with the LEDs mounted on the board. Here are all the STL files. FujinetTHcase.zip 2 Quote Link to comment Share on other sites More sharing options...

Fierodoug5 Posted May 2, 2021 Share Posted May 2, 2021 (edited) This is the remote box for my Fujinet through-hole 1030 modem that will mount on top of my monitor so: A) I do not have to make any holes in the Atari 1030, the remote wiring will exit out the square hole in the back where the phone jack was. B) I will have easy access to buttons, Micro SD card and activity LED's. The (2) LED's on the Atari 1030 will work as Power, and WIFI. And the Switch on the 1030 will turn Fujinet on and Off(will be using external USB power) More to come as I slowly make progress on my version of the Atari 1030FN Edited May 2, 2021 by Fierodoug5 2 Quote Link to comment Share on other sites More sharing options...
