README
README.mdSPINC - DIY Automatic Battery Charger
Overview
SPINC is an Open-Source NiMH charging station that can automatically load and eject AA battery cells. Simply drop batteries into the top of the device, regardless of their polarity. The internal mechanism picks up one cell at a time and fast-charges them sequentially. Up to 7 fully charged batteries can be conveniently stored inside the device for easy access. In addition, SPINC doubles as a desk clock, displaying the date and time on its high-resolution LCD.
Features
- Fast-charges AA NiMH cells at up to 1A
- Automatic cell loading and ejection
- Electronic polarity-correction
- Voltage, temperature and charge time monitoring
- 240x400px monochrome LCD
- Date and time display using LVGL interface
- Compact and fully 3D-printed

Questions
How big is the SPINC AA Charger PCB?
It measures 70 × 72 mm and has 4 copper layers, 1.57 mm thick.
What parts does the SPINC AA Charger use?
101 parts, built around the RP2040, VCNL4040M3OE, W25Q64JVZPIQ and AP2112K-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SPINC AA Charger KiCad files?
From the CoretechR/SPINC repository on GitHub, at the commit this page was made from: the board is PCB/SPINC AA Charger/SPINC AA Charger.kicad_pcb and its schematic PCB/SPINC AA Charger/SPINC AA Charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SPINC AA Charger design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
