First steps with Beaglebone Black

embeddedguy

I have got the BB Black for a while but never got time to get started. It is different from Raspberry Pi in some sense.The thing which I liked is that it can boot from an onboard emmc memory chip. This means you do not need to install OS onfragile SD...

UPDATE: under 40 degrees C!!! Lowest idle cpu temp so far on the BeagleBone AI SBC! how-to and pictures inside

clickio

OK, it shouldn't be a surprise to anyone that this board gets H-O-T. It's not something to be held in the palm of your hand, so it's not that critical. Until it is. Because, as all/most CPUs, it halts when reaching a certain temperature in order to p...
