Nope. 2G is used for all voice transmission in 3G and 4G/LTE. It's also used for services like automated emergency calls after a car accident. If something gets migrated for the use of 5G, it's rather 3G. 0 Quote Link to comment Share on other sites More sharing options...

Not quite accurate - 2G (GSM/GPRS) is a completely different radio access network, including waveforms and modulation scheme. 2G was turned down some time back here in the US, and now the major operators have scheduled the 3G sunset in the next couple. 1 Quote Link to comment Share on other sites More sharing options...

sfx2000 Posted October 27, 2019 Author Share Posted October 27, 2019 Quick update on DingleBerry Pi... Schematics - done - It's essentially a respin of the QC/Atheros reference design into a Pi board form factor. Layout/Gerbers - done - 4 layer board, single sided - nice to have a friend with an Orcad license from Cadence. Specifics MIPS24kc @ 650Mhz - big endian 802.11n - ATH9K driver - 2*2:2 for 300Mbps at 2.4GHz (wide channels) - PCB trace antennas Two 100Base-2 Ethernet - WAN dedicated port, LAN on switched port One USB-A for peripherals MicroUSB for Power/Console 32MB SPI-NOR flash - uboot and OS 128MB SPI-NAND flash - extending FS for application and user space 64MB DDR2 RAM SW - OpenWRT Master on the ATH79 target Bootloader - uboot with Pepe2K mods (web server fail-safe) The 4351 does have PCIe, but I've decided not to implement Performance Targets: Reference board is good for 100Mbps WiFi and NAT LAN/WAN performance so fairly balanced there. Power - 5V5DC, 1000ma for PS - right now with everything active on reference design, we're around 850ma at max load. BOM is reasonable, COGS says we're around $50USD to cover the NRE and breakeven with 1K boards with kits (box, cables, boards, ac adapter) I will not build/ship at a loss... So the next step before doing the engineering sample boards it to gauge the potential market interest. 2 Quote Link to comment Share on other sites More sharing options...
sfx2000 Posted October 28, 2019 Author Share Posted October 28, 2019 Have been exploring Dingleberry Pi 2 QC/Atheros IPQ4019 - more relevant here for the ARM folks - IPQ4019 is a quad core Cortex-A7@800MHz Buys us GigE on WAN/LAN ports, along with ATH10K for dual-band 802.11 a/b/g/n/AC Wave2 along with USB3.0 for the USB user facing port. BOM cost is higher, as it manf. costs with more layers, and more power needs - and numbers there do not make sense for an affordable board for this community - $100 GOGS there... 1 Quote Link to comment Share on other sites More sharing options...

I dont think you will sell so much, that you can make profit That's the challenge - I can do a DNI on the SPI-NAND, which takes a couple of dollars off... moving to 16MB NOR brings prices also down a bit - saving about 2 bucks Moving from QCA4351 to MT7628NN saves one dollar, but not worth the frustration there of re-doing schematics/layout and more NRE - so that's a non-starter, not to mention having to establish ties into the MediaTek ecosystem - I have good logistics into the Qualcomm and Marvell arena based on past projects. So that knocks 3 to 4 dollars off the BOM - moving manf from US to Shenzen drops conversion costs (cost to make the boards), but not enough to offset the shipping to distribution here in the US. Anyways, as @guidol points out - it's a narrow focused product, so volume isn't going to be very high. 0 Quote Link to comment Share on other sites More sharing options...

I have to put my program manager hat on - the numbers don't work with potential volume, so I'm putting the project idea on the shelf for now. That being said - there are a number of boards that are suitable and similar in concept - and they available now. these boards are hacker friendly, accessable, and supported. GL-iNet AR150 - This is a QCA9331 MIPS24Kc @ 400MHz, 64MB DDR2, 16MB SPI-NOR GL-iNet AR300M - QCA9531 MIPS24Kc @ 650MHz, 128MB RAM, 128MB SPI-NAND and 16MB SPI-NOR, there's a couple of variants there - one with no NAND, the 16M, and the lite, which is single ethernet. AR150 is fully supported on OpenWRT ar71xx, and is very affordable, and a cool hacker board due to the open nature of the CPU and more importantly, the ath9k radio, along with a robust uboot implementation. 0 Quote Link to comment Share on other sites More sharing options...
markbirss Posted November 6, 2019 Share Posted November 6, 2019 @sfx2000 those GL-iNet devices are not bad. But not always cheap At around $ 3.39 used not bad as OpenWRT support was added earlier this year. I use my own mesh firmware on them https://openwrt.org/toh/aruba/aruba_ap-105 Hardware CPU Atheros AR7161-8C1A 680 MHz Flash size 16 MiB RAM 128MiB Wireless Atheros AR9220-AC1A, Atheros AR9223-AC1A Ethernet Atheros AR8021-BL1E 10/100/1000 PoE USB No Serial Yes Power: POE or dc jack or Used Cisco Meraki MR24 between $ 10-20 https://openwrt.org/toh/meraki/mr24?s[]=mr24 0 Quote Link to comment Share on other sites More sharing options...
sfx2000 Posted November 6, 2019 Author Share Posted November 6, 2019 true, true... and that was one the market barriers to entry. the ar150 is easily available on the various sales portals (amazon/alibaba/etc), and relatively affordable - they typically run in the $20-25 USD range, which for a board of that price, is actually a lot of bang for the buck - ar150 is essentially the QC-Atheros AP-121 platform at a firmware level. OpenWRT direct support is very good - and the ath9k driver makes it even more so... 0 Quote Link to comment Share on other sites More sharing options...
guidol Posted April 14, 2020 Share Posted April 14, 2020 A new(?) V3s-like SBC: Daniel Palmer's BreadBee is based on a relatively unknown IP camera SoC, the MSC313E i.e. the AllWinner V3s is very similar to the SoC used here but it only has one SPI controller that is lost as soon as you put SPI NOR on it. https://www.hackster.io/news/daniel-palmer-s-breadbee-is-an-ultra-compact-1ghz-arm-cortex-a7-sbc-with-on-board-ethernet-577cab543154 0 Quote Link to comment Share on other sites More sharing options...
guidol Posted May 13, 2020 Share Posted May 13, 2020 For Retro-reasons: I did buy a old Acme Systems FOX G20 (because it was cheap (10EUR) - normally I would like own a Acme Systems Arietta G25 because of the formfactor / pinout). The Fox has only 400Mhz and 64MB of Ram (Arietta has 128 or 256MB but same CPU-Speed) but could boot a wheezy (Sorry no armbian) in 9MB I do find it very cool this very low memory useage - while running the SSH/FTP-Server. Also I like the company name Reminds me at the companys allways could be seen in Cartoon series (ACME Co. = https://en.wikipedia.org/wiki/Acme_Corporation ) The original image on the companys webpage was "infected" with emdebian wheezy-grip which is long EOL So I had to multistrap a new rootfs from the pure debian archive wheezy and transplant the modules/firmware to the newer rootfs (kernel is the same). Was something nice to learn here while staying home 2 Quote Link to comment Share on other sites More sharing options...

Maybe in his design - but SPI can support multiple slaves... only one master of course... Here's a couple of different topologies using SPI and multiple slaves - I did something similar a few years back with SPI-NOR and SPI-NAND for expansion... there, each devices was and MTD device, using UBI and formatting with UBIFS - bootloader, kernel, rootfs on the NOR, storage on the NAND I've seen crazy stuff on SPI - everything from MUX's to Switches, to doing a Serial-Parallel converter... 0 Quote Link to comment Share on other sites More sharing options...
