What is PN Mini?

PN Mini is a family of high performance, easy-to-use DC/DC Power Modules for DIY electronics.
PN Mini can be used as positive supply or negative supply. If both positive and negative supply rail are needed, just connect two PN Mini modules together. No hardware changes are required.

PN Mini is available in a small PCB package that enhances thermal performance and allows for hand soldering or plugin use. It provides +3.3V/-3.3V, +5V/-5V, or +12V/-12V output directly to your circuits requiring no external components.
PN Mini family has two output current options to meet your system needs:

PNMini-500mA: supports up to 500mA output current
PNMini-2A: supports up to 2A output current

Find the DATASHEET!
Shown in the figure below is a PNMini-2A module. All the application instructions given below use PNMini-2A as an example. The PNMini-500mA version is similar in terms of how to use. Detailed specifications and test data of PNMini-500mA will be available after the final test is done.

How do I use it?

Supply Rail Configuration
PN Mini is extremely easy to use. There is no external component required. The three terminals of PN Mini are input voltage VIN, output voltage VOUT, and ground connection GND. The VIN pin is always fixed as Pin 3. Depending on the system requirements, Pin 1 can be positive output VOUT(+) or GND; Pin 2 can be GND or negative output VOUT(-).
Input Range
The input range of the PN Mini family is very wide to cover more DIY electronics applications. For PN Mini-2A, the input range for positive output is 3.5V to 27V. The input range for negative output is 2.7V to 27V.
Output Programming
The output voltage is programmable through three feedback resistors connected from VOUT terminal to GND terminal.

1. Arduino drone with longer battery life

PN Mini can be used to power your Arduino drone. A miniature Arduino board is usually powered by 3.3V. The motors and sensors are usually 5V. You can use 3 li-ion battery stack and two PN Mini to get the voltage you want! It’s more efficient than LDO. PN Mini provides up to 92% efficiency while LDOs can hardly achieve more than 50% efficiency. That’s a 40% longer battery life for your design!
