## Description

Description:Witty Pi 3 is the third generation of Witty Pi, and it is the upgraded version of Witty Pi 2. It adds realtime clock (RTC) and power management to your Raspberry Pi, and can define complex ON/OFF sequence with simple script. Witty Pi 3 supports all Raspberry Pi models with 40-pin header such as 4B, 3B+, 3B, 3A+, 2B, B+, A+, Zero, Zero W.Witty Pi 3 uses the same RTC chip (DS3231SN) as compare to the Witty Pi 2 and it comes with a new micro-controller (ATtiny841), which enables it to act smarter and handle more complex situations. Thanks to the new on-board LDO voltage regulator (LM29150), Witty Pi 3 can acknowledge DC voltage higher than 5V (up to 26V, depends on the load and heat sink).Specifications:Dimension: 65mm x 56mm x 19mm (Approx.)Weight: 20g (net weight without battery)Battery: CR2032 (for time and alarms keeping)Static Current: ~1mAOperating Temperature: -30℃~80℃ (-22°F~176°F)Storage Temperature: -40℃~85℃ (-40°F~185°F)Humidity: 0~80%RH, no condensingPower In: DC 5V (via micro USB) or DC 5.3V~26V (via XH2.54 connector)Output Current: Up to 3A for Raspberry Pi and its peripherals if input via micro USB port. Up to 2A if input via XH2.54 connector.Box Contains:1 x Witty Pi 3 board1 x CR2032 battery4 x M2.5 x 11mm Copper Standoff8 x M2.5 screws

## Features

- Make sure this fits by entering your model number.
- Witty Pi 3 can power the Raspberry Pi with higher voltage. And can gracefully turn on/off Raspberry Pi with single tap on the switch.
- It helps Raspberry Pi to know the correct time, even without accessing the Internet, also it helps to get the temperature - thanks to the sensor in RTC chip.
- It can schedule the startup/shutdown of the Raspberry Pi. And it can even write a script to define complex ON/OFF sequence.
- It shut down the Raspberry Pi when input voltage is lower than pre-set value. And turn on the Raspberry Pi when input voltage raise to pre-set value.
- When the OS loses response, It can long hold the switch to force power cut.
