Specification
• The EEPROM can be disabled and its I2C address changed for increased compatibility with other boards
• BP7X battery - original battery from Motorola Droid 2 (A955) - 1820mAh battery
• Microcontroller is an ST Micro STM32F030CCT6 ARM Cortex-M0, 48MHz, F64KB, R8KB, I2C, SPI, USART,
2.4-3.6V
• Charge IC - BQ24160RGET Charger IC Lithium-Ion/Polymer, 2.5A, 4.2-10V
• Fuel gauge IC - LC709203FQH-01TWG Battery Fuel Gauge, 1-Cell Li-ion, 2.8%
• EEPROM - CAT24C32WI-GT3 EEPROM, I2C, 32KBIT, 400KHZ, 1V7-5V5
• Optional spring pin - Mil-Max 0929-7-15-20-77-14-11-0
• Compatible with any 4 pin battery on board that can be used with 00-9155-004-742-006 battery contacts
from AVX including the BP7X, BP6X, and any compatible batteries including the 1600mAh and 2300mAh
ones from CameronSino (CS-MOA853SL and CS-MOA855XL)
• There is an on board 4 pin screw terminal block for larger off board batteries. Any single cell LiPo / LiIon is
compatible. However, you use your own sourced battery at your own risk. We HIGHLY RECOMMEND using a
battery with an internal protection circuit and a NTC (temp sensor)
• Optional header for offboard button - connected to same output as SW1
6 pin breakout header - with two GPIO from the ARM Cortex-M0, Vsys, 5v0, 3v3, GND connections
• Header for optional off board solar panel / wind turbine etc.
Optional RF Shield attachment - Harwin S02-20150300 (can also double as an inexpensive heatsink)
• Input voltage range - 4.2V 10V
Output voltage - 3.3V and 5V
• Output amperage - maximum current at 5V gpio is 2.5A and at VSYS output 2.1A, but also this depends
heavily on battery capacity. For BP7X have measured around 1.1A at 5V GPIO and around 1.6A at VSYS
output. Obviously, this also depends heavily on the current draw demanded by the Raspberry Pi/device itself.
To achieve a maximum of 2.5A it will need battery over 3500mAh.
