For those who didn't read TFA: No clones? Orange Pi, Banana Pi, Nano Pi, Mango Pi, Lychee ... Admittedly not Broadcom chips (a good thing, IMHO), but SBC's

For those who didn't read TFA: No clones? Orange Pi, Banana Pi, Nano Pi, Mango Pi, Lychee ... Admittedly not Broadcom chips (a good thing, IMHO), but SBC's running Armbian and usually having GPIO which ape the RasPi 40 pin header. Broadcom chips aren't Open Source, Arduino are, so Allwinner and Rockchips are used instead of the expensive and/or difficult to acquire proprietary ones meaning no like for like clones.
