ProtoMate for XIAO and QT Py is a breadboard-style prototyping board for any Seeed XIAO or Adafruit QT Py dev board (not included), designed to give you an easy way to make projects more permanent and reliable, moving from loose jumper wires and breadboards to a proper soldered PCB!
The ProtoMate has a main 14x8 breadboard-style soldering area with central rails, i.e. the pads/holes are connected in lanes. Some customers prefer this style, and some prefer the disconnected, perfboard-style. If perfboard-style is more your thing, check out the PerfMate for XIAO and QT Py instead.
The XIAO's GPIO pins are broken out in order along the top of this prototyping area, making it easy to connect to the IO you need. The central rails are split as indicated by the white frame, but are easily bridged with solder if you want to connect them.
The ProtoMate also includes connected rails on each side of the board, great for making banks of power pads for your project. These are connected in lanes, indicated by the gold pad bridges and white frames. You can cut the trace bridges between the rail pads if you want to disconnect them from each other.
Plan your circuit and pins (then check it at least twice!), fit your components to the board, then solder them along with any prototyping wire connections.
You can mount your XIAO in different ways depending on your needs:
XIAO and mounting hardware (standoffs) not included.
Our product team spent time considering how to make this the most useful XIAO protoboard available:
🏁 Large main breadboard-style soldering area with split central rails (14x8)
📌 IO pins broken out in order
🛤️ Rails on each side of the board to make banks for regularly used pins (such as 5V/GND)
🪙 ENIG (Gold) PCB plating for oxidation resistance and durability
↕️ 'Rear Side' label to remind you which way up to solder the board
🔩 M2.5 mounting holes, easily sourced and not too fiddly
💸 Two 7-pin female headers included!
Recommended standoffs - M2.5 female/female standoffs with M2.5 screws.
XIAO and mounting hardware (standoffs) not included.
