• Battery type: 1S (single-cell) LiPo
• Charge current: 100mA
• Charge voltage: 4.2V
• Power Input: 5.0V
• Outputs: 3.3V & 5.0V
• Charger: MCP73832
• Booster: MCP1642
• Charge status (On-Off) digital output
• Battery-level analog output
• Onboard switch to disconnect output

The CHARGING output pin is active-low (0 = Battery is charging / 1 = Battery is not charging).

The BAT LEVEL output is the analog voltage measured at the battery, scaled down to 3.3V.
