Locker1
About the Locker1 PCB
Locker1 is an open source PCB design by adsehgal, published on GitHub. It is a 2-layer board measuring 90 × 73 mm, with 38 components from 22 distinct parts.
Other key parts include the LM2576_DB, TS5A3357 and TL081. By type, the board carries 10 resistors, 8 connectors, 7 ICs, 6 capacitors, 4 diodes and 1 transistor.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
This repo collates my senior design project at UCSC.
SlugCharge was a student run project geared towards helping the homeless communit of Santa Cruz, CA. The project was led by four Electrical Engineering students at the University of California, Santa Cruz. The team aimed towards providing solar powered charging stations to the community so they can stay conencted with family and potential employers that may turn their life around!
