    * solder bridge next to power switch. Can cause problems since poweroff-feature. To fix this blacklist pmic-keys-module or uninstall acpid package see [[https://github.com/frank-w/BPI-R2-4.14/issues/35|issue 35]]
    * input 5V to OTG
  * poweroff (4.14.53+) needs acpid package for power-button (command works without it)

{{:bpi-r2:sata_power.jpg?direct&50|}}

it works with GND next to power (1+2,3+4). 12V is yellow, 5V is red

both jacks near sata-connector have voltage, also if R2 is "halted", the fan-jack (near IR-receiver) had no direct-current output in my tests (4.14), this seems my gnd there is broken...with another gnd i have the 5V output
