"There is no HDMI support, you’ll need to add some more chips (that are probably in a BGA package), but, hey, it’s only a dollar."
And a power supply, IO, RAM, ROM, board, etc. The BOM quickly adds up.
I don't know what the price of the RPi CPU is, but my guess is it's not far off $1 in bulk.
- MrEfficiency 8y agoThis was my thought, its cool, but you will still need to buy things for power management at a minimum. Anyone have a drawing? Curious if it NEEDS capacitors to function.
- pjc50 8y agoIt will do, almost every digital IC will require decoupling capacitors for stable operation.

- tyingq 8y agoBroadcom has a very high minimum order quantity. There's also an onerous license that won't allow you to use the Rpi software if you build your own broadcom board. https://github.com/raspberrypi/firmware/blob/master/boot/LICENCE.broadcom https://github.com/raspberrypi/firmware/blob/master/boot/LIC...
- makomk 8y agoAlso, you more or less need the binary blob with the license agreement that forbids use on non-Pi boards in order to boot that chip. It runs on an undocumented CPU architecture and initializes a whole bunch of undocumented but essential hardware. There's an open source replacement which is just barely capable of booting Linux and giving a serial console, but the developers basically gave up and recommended people use something like one of the Allwinner chips instead.
