2 Planned Changes for V2
- DC barrel connector attached directly to the PB with a cable
- mechanical trimmer (discontinued) replacement -> switching regulators with digital voltage control
- PICO SPOX power input connector will be moved "into" the PB so the cable can be routed inside the camera enclosure towards the backside
- RGB LED and pushbutton (ALPS SKSNLAE010 currently considered) moved from smart power adapter to PB camera orientation top/left side

4 Calibrating Voltages
This describes the process required when factory assembling the power board hardware in the AXIOM Beta stack.
./power_init.sh
./power_on.sh
wait a bit
./pac1720_info.sh
This will output something like:
ZED_5V 4.8828 V [1f40] +10.1562 mV [104] +677.08 mA BETA_5V 4.8828 V [1f40] +1.2891 mV [021] +85.94 mA HDN 3.2812 V [1500] +0.0000 mV [000] +0.00 mA PCIE_N_V 3.2422 V [14c0] +0.0000 mV [000] +0.00 mA HDS 3.2031 V [1480] +0.0000 mV [000] +0.00 mA PCIE_S_V 3.2422 V [14c0] +0.0000 mV [000] +0.00 mA RFW_V 3.2422 V [14c0] -0.0391 mV [fff] -2.60 mA IOW_V 3.2617 V [14e0] +0.0000 mV [000] +0.00 mA RFE_V 3.2422 V [14c0] +0.0000 mV [000] +0.00 mA IOE_V 3.2812 V [1500] +0.0000 mV [000] +0.00 mA VCCO_35 2.4219 V [ f80] -0.0391 mV [fff] -2.60 mA VCCO_13 2.4609 V [ fc0] +0.0000 mV [000] +0.00 mA PCIE_IO 2.4609 V [ fc0] -0.0781 mV [ffe] -5.21 mA VCCO_34 2.4609 V [ fc0] +0.9766 mV [019] +65.10 mA W_VW 2.7734 V [11c0] +0.0000 mV [000] +0.00 mA N_VW 2.8125 V [1200] +0.0000 mV [000] +0.00 mA N_VN 2.7734 V [11c0] -0.0391 mV [fff] -2.60 mA N_VE 2.8516 V [1240] +0.0000 mV [000] +0.00 mA E_VE 2.6953 V [1140] -0.0391 mV [fff] -2.60 mA S_VE 2.8516 V [1240] +0.0000 mV [000] +0.00 mA S_VS 2.7344 V [1180] -0.0391 mV [fff] -2.60 mA S_VW 2.8516 V [1240] -0.0781 mV [ffe] -5.21 mA
now run:
watch -n 0.2 ./pac1720_info.sh
which will display the voltages in a clear screen and constantly update the values until you press CTRL+C
The PCB labels and the labels in the CLI correspond like the following:
WW = W_VW NW = N_VW NN = N_VN NE = N_VE SW = S_VW SS = S_VS SE = S_VE EE = E_VE
Use a tiny screwdriver and adjust the trimmers on the PCB until your values look like this:
W_VW 2.4609 V [ fc0] -0.0391 mV [fff] -2.60 mA N_VW 3.2422 V [14c0] +0.0000 mV [000] +0.00 mA N_VN 1.8750 V [ c00] -0.0391 mV [fff] -2.60 mA N_VE 3.2617 V [14e0] +0.0000 mV [000] +0.00 mA E_VE 3.2812 V [1500] +0.0391 mV [001] +2.60 mA S_VE 1.9922 V [ cc0] +0.0000 mV [000] +0.00 mA S_VS 2.9883 V [1320] -0.0391 mV [fff] -2.60 mA S_VW 1.9531 V [ c80] -0.1172 mV [ffd] -7.81 mA
