This is a Raspberry Pi Shield. 12V DC to input. The board will power the Pi through the GPIO using a switch power supply based around the ACT4065A IC. The input 12V comes in through the DC "IN" barrel Jack. Then is turned on and off through the TIP120 NPN Transistor which is controlled through GPIO 4 on the Pi and outputs the barrel Jack labeled "OUT". There is also another TIP120 NPN transistor controlled by GPIO 17 on the Pi. This output is soldered on the board. There are also onboard 4 onboard LED's:

When 12V is connected properly When 5V is converted properly When GPIO 4 is HIGH and Transistor is working When GPIO 17 is HIGH and Transistor is working P1,P2 DC-005 5.5-2.0MM (Barrel plug) H1 2*20P 2.54mm (40 pin Header) Mount on bottom side of board R4 12K (805 package) R5 10K (805 package) R1 52.3K (805 pacage D1 SB240 (DIODE) C1 100uF (5x11 Cap) U1 ACT4065ASH-T R2 1KΩ (805 package) Q1 TIP120 (NPN Transistor) R3,R6,R7 560 (2010 package) L3 33uH (6020 package) C5 1.5nF (805 package) LED2,LED1,LED3 FC-3215UGK-520D (1206 package) C2 10nF(103) (1206 package) P2 DC-005 5.5-2.0MMLED OUTPUT C4 47uF (5x11 CAP) R8 1k (805 package) MOUNTED ON BACK image.png
