About the Battery PCB
Battery is an open source PCB design by nzevh, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 222 × 24 mm, with 47 components from 24 distinct parts.
Other key parts include the TPD4E004DRYR, NXFT15XH103FA2B025 and BQ40Z50RSMR-R2. By type, the board carries 18 resistors, 9 capacitors, 6 ICs, 3 transistors, 2 connectors and 1 diode.
It belongs with the power & battery and dev boards & breakouts designs in this gallery.
From the project
fully open source laptop based on the RK3588 Soc
barebones is a work-in-progress open-source laptop motherboard project built around the Rockchip RK3588 platform. It is designed as a high-performance, modular laptop mainboard with dual DDR4 memory slots, hierarchical subsystem schematics, and a full laptop-oriented power, I/O, audio, and control architecture.
barebones is intended to be a complete laptop motherboard platform rather than a small breakout or development board. The design is organized into multiple schematic sheets that separate major functional blocks such as power delivery, memory, high-speed I/O, embedded control, audio…
