Battery module with LTO cells. This module was primarily designed for use in autonomous outdoor devices powered by a solar cell. This is possible thanks to the use of LTO cells, which have a wide range of operating conditions and require minimal care. The device can therefore work in outdoor conditions all year round (tested in Central European conditions).
Features:
- LTO batteries (4x LTO1865) cells
- 1.3 Ah (per cell)
- MPPT tracker for LTO batteries charging from solar cell
- Battery gauge for battery charge state measurement
- I2C interface
- LED indication
- Output switching voltage regulator
- Standard output voltage 3v3

Questions
How big is the SOLARMINIBAT01 PCB?
It measures 80.8 × 70.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SOLARMINIBAT01 use?
79 parts, built around the SPV1040T, BQ34Z100PW, SN74HC164D and 15MQ040N. 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 SOLARMINIBAT01 KiCad files?
From the mlab-modules/SOLARMINIBAT01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/SOLARMINIBAT01.kicad_pcb and its schematic hw/sch_pcb/SOLARMINIBAT01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SOLARMINIBAT01 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).
