Raspberry Pi Pico W

Ref. X

リチウムコイン電池CR2025(3V)を＋がVSYS、ーが隣のGNDに当たるように挟んでいます。
VSYSは1.8～5.5Vを流すと電源がつきますが、アルカリボタン電池(1.5V)だと微妙に足りない。
- アルカリボタン電池: LR
- リチウム電池(一次電池): CR、BR
- リチウム電池(二次電池): VL、ML、TC、CLB、MS、MT、UT

A lithium coin battery CR2025 (3V) is sandwiched between the two so that the + side is connected to VSYS and the - side is connected to the adjacent GND.
VSYS powers on when 1.8 to 5.5V is applied, but an alkaline button battery (1.5V) is slightly insufficient.
- Alkaline button battery: LR
- Lithium battery (primary battery): CR, BR
- Lithium battery (secondary battery): VL, ML, TC, CLB, MS, MT, UT
