While solderless breadboards are ideal for building temporary circuits, there comes a time in some projects where it is desirable to build a version that can be put into permanent use.
The most common option is to use standard 0.1” solder type perf board. While it is the least expensive approach, it generally gives unsatisfactory results for all but the simplest of circuits and the end result is almost guaranteed to be cosmetically challenged. There are also slightly better approaches that more or less duplicate the solderless breadboard in copper which have some of the same limitations as the solderless breadboard or which are designed to mount only a specific MCU.
We think there is a better approach and this third product in our Pro Series line of proto boards is the MCU Proto Board with 3.3 and 5V Power.
Our goal is to provide a high quality, easy to use board with a flexible architecture that works with virtually any DIP style MCU and that allows you to create a finished circuit that both functions well and which you will be proud to show off.
This 4.3” x 4” board utilizes high quality double-sided construction with ENIG (Electroless Nickel Immersion Gold) finish for maximum performance and good looks.
The center proto area is extra wide with a 6-hole pattern to accept virtually any DIP style microcontroller module such as the Arduino Nano and Micro, the full Teensy product line, ESP8266 NodeMCU, D1 Mini and ESP32 style development boards that tend to be extra wide. It will also work with any 0.3″ DIP package microcontroller ICs such as the ATTiny85 and ATmega328 if you want to build a microcontroller setup from scratch.
Standard 0.3” wide 3-hole proto sections provide mounting for standard DIP ICs, discrete components, modules of various types and SMD to DIP adapter boards.
There is also a 28-pin SOIC footprint on top and a mirrored TSSOP-28 footprint on the bottom side of the board for easily wiring in one large or several smaller SMD ICs.
Standard 0.1” header and offset connector footprints with separate solder points are provided along the back edge for easy I/O connections.
A flexible DC power input section provides includes multiple options for powering the board from an AC/DC adapter or battery. The input powers a 3.3V and 5V LDO regulator which can be used to supply power to the power rails on the board. The 5V is also useful for powering MCUs that operate at 3.3V and require a 5V VIN input like the Teensy product line. The power and ground rails fully covers the board.
The board comes with the power section fully assembled. Check out the product page for more product details
