5. Klangnetze Modules

Trópos was specifically composed for the Klangnetze system, and to interface with its hardware.

Hardware

Each Klangnetze module is built around a Raspberry Pi Zero 2W with a dedicated sound card that connects to a MEMS microphone and a small loudspeaker. This is powered by a single 18650 Li-Ion 2300mA battery, which collects its charge through a custom built-in 10W photovoltaic module.

 

Power Cycle

Power cycling is managed according to sun and battery conditions, so that the whole system is operational only at day time and with a decent amount of charge.
