The Beta Power Board sits between the Beta Main Board and the MicroZed™ in the cameras PCB stack. It generates all the different supply voltages for the chips and logic on the other PCB’s inside the camera. It also monitors currents so that it can estimate remaining power based on the recorded consumption. Version 1 of the Beta Power Board has the 8 different voltage rails calibrated at factory. In case of a future hardware upgrade that require any power rail to have a different reference voltage this calibration needs to be redone.

Structural changes:
Current: AXIOM Beta Power Board v0.30
Archive:
axiom beta power board v0.22 test
axiom beta power board v0.17 test
axiom beta power board v0.11 test
axiom beta power board v0.8 test
axiom beta power board v0.9 test
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
