CR1632を二個のせられます。並列的に繋いでいるので、1個の電池のみで動かすことも出来ます。
組み立て上の注意点
-
コイン電池ホルダの突起を基板側のシルクに合わせる
-
電池ホルダ間のクリアランスが狭いのでショートしないようにする
-
電池ホルダの足を折り曲げると背が低くなる
-
ダイオードの向きに注意(ダイオードのカソード(ラインが入ってるほう)がシルクのマーク側)
-
電源出力のマイナス側は出っ張らないようにする(電池の取り付け・取り外しができなくなる)
-
他の基板と接触する部分(作例だと裏面)はテープなどで絶縁する

Questions
How big is the Bmp battery PCB?
It measures 17.8 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bmp battery use?
8 parts. 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 Bmp battery KiCad files?
From the sekigon-gonnoc/BLE-Micro-Pro repository on GitHub, at the commit this page was made from: the board is CoinCellHolder/bmp_battery.kicad_pcb and its schematic bmp-boost/bmp-boost-extender/bmp-boost-extender.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bmp battery design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
