cables

wifi

  • rp-SMA to IPEX/u-FL cable for wifi-antennas

SATA

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

battery

  • 1,25mm SH 6pin for battery AliExpress, no circuit known battery-connector does not work see here

mount

  • wifi mPCIe-card bolted with M2x10 screws and knurled nut + 2 x washers of Polyamid (isolation+protection of the board)
