Re: OpenWrt One - celebrating 20 years of OpenWrt
And in the interest of running *my* own mouth, I'm stoked as hell -- LOVE that it will have mikroBUS! Thanks to John and everyone working on this! My only request is that any unused gpios that don't make it to mikroBUS find their way to a (possibly unpopulated) header some where for the sake of hackability. 1mm pitch is fine. I've had more than one occasion where I wanted to add something and didn't have the bus or I/O lines and then discovered that the MCU did, but they were all N/C. Hackability is what makes the FOSS / open hardware world so awesome.\! Daniel yeah we will add all remaining GPIO togehter with GND and 3,3V on a 2.54mm header. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

It wouldn't enable both interfaces to be used at the same time, but it would make it possible to select which interface is enabled using a GPIO pin. Then U-boot could either automatically enable one port or the other depending on what devices it detects (e.g., enable PCIe and disable USB 3 if a PCIe device is connected, otherwise enable USB 3 and disable PCIe), or it could be statically configurable via a U-boot environment variable. From some quick searching, the switches/muxes that would enable this cost less than $1 each in qty. 1000. For a <$100 product I understand that may be too much of an increase to the BoM cost and PCB complexity, but I think users would really appreciate being able to choose between being able to add an M.2 SSD, WiFi card, or SATA controller and being able to plug in a USB 3.x 2.5 GbE adapter, SSD/flash drive, WiFi dongle, or 5G modem. All the best, Forest I'm always a fan of a single PCB design that *can* be built in different configurations. So would suggest a design where differential mux can be left unpopulated to create a product w/o USB 3 support. But of course, this doesn't overcome EMI concerns Daniel Golle mentioned.

"Geeks" are good at commenting on stuff, and intellectualizing a new board: let's see how many put their money where their mouth is. I, for one, think the new board's a great idea, although I'm still happy with my Archer. I do feel that an upgrade in the next 12mo may become necessary, however. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
