Prototyping Shield for Arduino Micro with SMD footprints SO08, SOT223 and SOT23
Have you ever been frustrated creating a prototype using a simple MOSFET or 8-pin chip that’s only available in SMD? This Micro Proto Shield is the answer, for the Arduino Micro platform.
Information on the board
All Arduino pins are labelled on both sides of the board. The Arduino symbol and the ISP header outline are provided to help you plug in the Micro the correct way around.
All wires to the SMD footprints are shown in white on the silkscreen so you can quickly see which hole connects to which SMD pad.
N-channel MOSFETS connected to PWM pins
The two large MOSFET footprints Q1 and Q2 are already connected to the first two PWM pins (3 and 5) on your Arduino. Source is connected to grounds and the Drain output has a prototyping hole connected to the large tab on the transistor.
The transistors require pullups to hold them in the off state while the Arduino bootloader is active. Footprints for 0603 size resistors are provided for R1 and R2. Or you can wire through-hole resistors to the pads adjacent to pins 3 and 5.
If the pinouts on your transistors are different, just cut the resolderable traces between the holes and wire them up how you want.
SOT23 footprints
The large SOT-223 transistors have enough space inside their footprint to include pads for SOT23 size transistors too: Q3 and Q4. The wiring is the same as common N-channel MOSFETS or you can cut the resolderable traces and wire it however you want.
SO-8 integrated circuit U1
This seems to be a common size for memory chips, thermocouple interfaces and a lot of other different chips. All 8 pins are broken out to holes, with no default wiring. Connect your chip any way you want.
95 free prototyping holes
There’s still a large number of free holes on the board, so a 14-pin DIL chip can be installed or anything else that fits. +5V and ground buses are provided at both ends of the board.
Check out the standard prototyping version too
I’ve also shared a version without the SMD footprints, if you need more conventional components.

Flexible prototyping shield for your Arduino Micro.
Only 0.2" longer and wider than the Arduino Micro. 139 holes ready for your components to solder in.
0.1" hole spacing will accept standard ICs, breadboard headers, DuPont connectors, TO220 transistors and more. Extra +5V and Ground rails are provided at both ends of the board. All Arduino pins are connected to two adjacent holes, with cuttable and resolderable jumpers. Every pin is labelled on both sides of the board.
Mounting holes are 2mm. Can be drilled out to 3mm or 1/8" if required.
The Arduino “infinity” symbol and the ISP outline is included to help you plug in the Micro in the correct orientation. It could fit both ways but then the labels will be wrong.
Also check out the SMD version that has some surface-mount component outlines available.
