3 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

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
