You may want to look again… if you click on the Cottonwood page, it lists related products including a 5V 3A power supply.
If you don’t like that one, I’ve had good results with supplies made by iUniker found on Amazon. They have 3A supplies with micro-usb and 4A with USB-C, both have integrated cables with in-line power switches.
Note: I don’t work for or represent any of these companies.
I would like to know more about the UEFI, I can’t find any solid information. Is the UEFI complete? Is the GPU exposed properly to loaded kernels? There are other SBC makers with UEFI that have neglected passing on information about the GPU and VPU, making the board useless for any form of hardware video encoding (h264, h265, etc) or hardware gpu acceleration (opengl, vulkan, etc). I need to know if this work has already been done. Can yall upload a video demonstrating the UEFI, and possibly showing a stock debian uefi arm64 image with panfrost mesa driver loaded?
And what is the reason for continuing to not include wifi on board? Is it because of the blob mess? I almost would rather have no wifi than the crap broadcom ships out like other sbc makers use… almost.
The onboard header for USB is great, theoretical 480Mbps for 2.0 should be fine for wifi. The only downside I see to the lack of wifi onboard is the current draw from a USB wifi device operating in access point mode.
EDIT: Looks like I was mistaken, there is no USB header on the alta or solitude.
