About the BMU switch mosfet PCB

BMU switch mosfet is an open source PCB design by KomplexKapharnaum, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 23 × 81.8 mm, with 18 components from 5 distinct parts.

Other key parts include the HX PZ2.54-1X2P ZZ and ZX-IDC2.54-2-5PZZ. By type, the board carries 10 transistors, 5 resistors and 3 ICs.

It belongs with the iot & wireless designs in this gallery.

From the project

The KXKM Batterie Parallelator is an embedded Battery Management Unit (BMU) that safely parallels multiple battery packs (24-30V) for off-grid stage installations. Each battery is individually monitored (voltage, current, temperature) and can be disconnected in microseconds via M

The KXKM Batterie Parallelator is an embedded Battery Management Unit (BMU) that safely parallels multiple battery packs (24-30V) for off-grid stage installations. Each battery is individually monitored (voltage, current, temperature) and can be disconnected in microseconds via MOSFET switches.

Built by L'Electron Rare for KompleX KapharnaüM (Villeurbanne, France) — a live arts company deploying digital scenography in public spaces without grid power.
