PowerPal Selectable Voltage 3-Amp Breadboard
Power Supply (#32133)
The PowerPal is a breadboard-friendly 3A power supply module that allows you to select from
four different output voltage levels. It's ideal for regula ng power to the Propeller FLiP Try-it Kit
or other breadboard based projects along with a ba ery pack or wall-mount supply. It comes
with two sturdy 2x2 headers which plug directly into the breadboard rail. Through-hole pads are
provided that allow the user to op onally add an addi onal VOUT header or on-off switch
leads.
Features
● Rotary switch for user-selectable voltage output choices: 3.3 V, 5 V, 6 V, 7.5 V
● 3 Amp con nuous load switching power supply
● 4 Amp peak surge ra ng is ideal for servo motors
● Barrel Jack or 0.1 inch pitch headers for 5-16 VIN
● Through-hole pads for op onal On/Off switch leads
● Green power-status LED
● Over-current and over-voltage protec on
● Over-temperature and short-circuit protec on
● 0.1 inch (2.6 mm) diameter moun ng hole

● Dimensions: PCB 1.5 x 1 inch (39 x 24 mm); 0.1 inch (2.6 mm) moun ng hole Feature Descriptions Read the full explana on of each labeled feature on the pages that follow this diagram. Copyright © Parallax Inc. PowerPal Module (#32133) V1.0 11/20/2018 Page 2 of 6... - Page 3 The 3-pin VIN header is connected directly to the DC Jack, and so care should be taken not to supply power into the PowerPal through both the DC Jack and the 3-pin VIN header at the same Located between the DC Jack and 3-pin VIN header are two addi onal unpopulated + VIN through-hole pads.
- Page 4 4) VOUT Breadboard Headers The PowerPal has two blocks of 4-pin headers posi oned to allow inser on directly into the breadboard power rail. The top pins are all posi ve voltage, and the bo om row of pins (nearest the board edge) are nega ve GND.
- Page 5 7) Switching Power Supply The center area of the PowerPal pcb contains the switching power supply IC and suppor ng components. CAUTION! Components will become HOT when supplying high current loads! TIP! The PCB is designed to act as heatsink, and the reverse of the PCB features a continuous 2 oz copper ground plane which will become warm in normal use.
