• 2 headers to enable/disable the internal LDOs
• 2 headers to disable the primary battery feature
• 2 resistors to define the primary battery minimum level
• 1 header to disable the dual cell supercapacitor balancing feature
• 1 resistors footprint to use the ZMPPT feature (constant impedance matching)
Size
• 76mm x 49mm
• 4 x M2.5 mounting holes
