situations. Thanks to the new on-board LDO voltage regulator (LM29150), Witty Pi 3 can accept DC
voltage higher than 5V (up to 26V, depends on the load and heat sink).
Witty Pi 3 doesn't have any jumper, and all configurations are done via I2C interface. Witty Pi's
software can help you to make configuration very quickly.
The picture below shows how is Witty Pi 3 look like:
1) Micro USB connector as DC 5V power input
2) XH2.54 connector as higher voltage DC power input
3) Unpopulated 3-pin header/connector for VIN, GND and 5V
4) White LED as indicator
5) On/off switch
6) 2x20 pin stacking header (connects to Raspberry Pi)
7) Unpopulated 2x3 pin ICSP header for uploading firmware
8) Battery holder for CR2032 button cell lithium battery
9) Unpopulated 7-pin header for extension or integration
