Powering the nodes is handled by a small Drok DC to DC buck converter. It’s a compact switching regulator, wrapped in Kapton tape for insulation and durability, and fitted with an XT60 connector for easy connection to battery packs. Using a buck converter allows the system to efficiently step down higher input voltages while keeping power loss and heat to a minimum, which is especially important when running low-power radio hardware for extended periods.
