What's On Board

 Pinout Definition

• IN Power input (5V 3A)
  
• OUT UPS output (5V 2.5A)
• GND ground
• UPS OFF turn off UPS power output when connected to PWR pin
• BOOT Batteries activation (pull low for 500ms and then pull high)
• CHARGE Charge indication (low level indicates charging)
• SCL I2C clock
• SDA I2C data
• PWR UPS ON/OFF (turn off UPS power output when connected to UPS OFF pin)

Note: When using pin headers for charging and discharging, it is recommended to connect all input and output pins for 2.5A output current to reduce pin stress

Resources for different product may vary, please check the wiki page to confirm the actually provided resources.

• Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
  
• Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
• Do not mix use old batteries with new ones, avoid using batteries of different brands.
• When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
• Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
• Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
