BAL Option: Select “CON” for dual-cells supercapacitor and “GND” for any other storage.
PRIM Option: Connect both jumpers “NoPRIM” or remove them if a primary battery is connected.
Define minimum voltage using R7 and R8.
- 100 kΩ RP < 500 kΩ
- R8=RP-R7
LDOs Output Voltages: ENHV [HVOUT] – ENLV [LVOUT]
| ENLV | ENHV | LV output | HV output |
| 1 | 1 | Enabled | Enabled |
| 1 | 0 | Enabled | Disabled |
| 0 | 1 | Disabled | Enabled |
| 0 | 0 | Disabled | Disabled |
Step 2: Connect the storage element or solder a CAP-XX supercapacitor on the bottom layer (refer to the table on the following page)
Step 3: Connect the Load(s) to HVOUT / LVOUT
Step 4: Connect the PowerFilm Photovoltaic module to SRC
Step 5: Set up complete! See User Guide for additional details and advanced configurations.

Table 7: Footprint description
This footprint is available on the inferior face of the PCB. The red colour represents the positive voltage, the blue is the ground and the black is to be connected to the balancing pin. Those three potentials are available on the screw terminal on the top side.
