PiJuice HAT

You'll still be able to track charge levels and other information with the two built-in tri-color RGB LEDs, trigger events and scripts with the three programmable buttons, and since the PiJuice will use up to five of your GPIO pins (just power and I2C), the rest is free to diversify your project. The stacking header allows you to continue using your existing HATs and add-ons with PiJuice.

Keep your Raspberry Pi running on solar, wind and renewable energy.

Ultimate embedded power is one thing, but what if we could run Raspberry Pi renewably? Solar, wind, thermoelectric and other renewable energy is free, clean and environmentally friendly and PiJuice is proud to have developed an affordable and efficient renewable energy solution for the Raspberry Pi!

PiJuice is self-monitoring and, like a space satellite, can become a completely autonomous system. Use the PiJuice as part of a stand-alone camera system, weather stations, off-grid workstations, and many other outdoor projects.

Technical information

• EEPROM can be disabled and its I2C address changed for increased compatibility with other boards
• Battery BP7X - original Motorola Droid 2 (A955) battery - 1820mAh battery
• Microcontroller is an ARM STM32F030CCT6 ARM Cortex-M0, 48MHz, F64KB, R8KB, I2C, SPI, USART, 2.4-3.6V
• IC Charger - BQ24160RGET Lithium-Ion / Polymer IC Charger, 2.5A, 4.2-10V
• IC Fuel Gauge - LC709203FQH-01TWG Battery Fuel Gauge, 1 cell Li-ion, 2.8%
• EEPROM - EEPROM CAT24C32WI-GT3, I2C, 32KBIT, 400KHZ, 1V7-5V5
• Optional spring pin - Mil-Max 0929-7-15-20-77-14-11-0
• Compatible with any on-board 4-pin battery that can be used with AVX battery contacts 00-9155-004-742-006, including BP7X, BP6X and all compatible batteries including CameronSino 1600mAh and 2300mAh batteries (CS-MOA853SL and CS -MOA855XL)
• There is a built-in 4-pin screw terminal block for larger off-board batteries. Any LiPo / LiIon cell is compatible. However, you use your own battery at your own risk. We strongly recommend using a battery with an internal protection circuit and an NTC (temperature sensor)
• Optional header for outboard button - connected to the same output as SW1
• 6-pin header - with two GPIOs of ARM Cortex-M0, Vsys, 5v0, 3v3, GND connections
• Header for optional off-panel solar/wind turbine etc.
• Optional RF Shield Harness - Harwin S02-20150300 (can also double as a low-cost heat sink)
• 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 this also depends strongly on the capacity of the battery. For BP7X measured around 1.1A at 5V GPIO and around 1.6A at VSYS output. Obviously, this also strongly depends on the current draw required by the Raspberry Pi / device itself. To reach a maximum of 2.5A, you will need a battery of more than 3500 mAh.
• Weight in box - 96g
• Box size - 12,2 x
