Hello, all.
I have finished soldering wires to pins 2 (5V Power), 12 (aka BCM18) and 20 (Ground) of Unicorn pHat according to the pin usage scheme at http://pinout.xyz/pinout/unicorn_phat#. According to Unicorn HAT + GPIO cable, I have already made one mistake - the ground should be connected to pin 9 (bit the resistance between pins 9 and 20 on the board is 0 Ohm - so I do not need to reconnect the wire).
Still, when I measure resistance between newly soldered pin 2 (5V) and pin 20 (Ground), I get measurements of around 2000 Ohm (the Unicorn pHat is not connected to anything). This number looks too small for me, and as I do not want to fry the Raspberry Pi by connecting this to it, I want to confirm if the 2000 Ohm is an expected number - or if I need to investigate my soldering job on those pins.
