Richard Meadows 7eef1f2783 [low-power-solar] complete IC section of partslist, board order 2016-03-30 15:18:40 +01:00
..
graphics Added new "simple" solar/primary design that just uses a LTC3105. Designed for use with a 1.5V primary lithium source. 2015-09-15 16:25:22 +01:00
hf-breakout Various bit rot on parts lists 2015-12-20 16:26:10 +00:00
internal Various bit rot on parts lists 2015-12-20 16:26:10 +00:00
