Assembled Terminal Block Breakout FeatherWing for all Feathers

by Adafruit

The Terminal Block Breakout FeatherWing kit is like the Golden Eagle of prototyping FeatherWings (eg. majestic, powerful, good-looking).

To start, you get a nice prototyping area underneath your Feather, with extra pads for ground, 3.3V and SDA/SCL. Not one to stop there, Adafruit expanded the PCB out to 2" x 2.5" with 3.5mm pitch terminal blocks down each side. There's also four mounting holes so you can attach the breakout to your enclosure or project.

This product works with all Feathers! The terminal blocks allow you to connect to any of the external Feather pins, great for wiring temporary or permanent installations. Adafruit also give you a few extra terminal block pins for ground and 3.3V connections since those are so useful. The terminal blocks included with your product may be blue or black.

Finally, there's a slide switch, which connects the EN pin to ground when in the 'off' position, cutting off the 3.3V regulator. Note that the FONA Feather uses both VBat and 3.3V as power supplies so you wont be able to fully turn off the FONA Feather with this switch.

Note: As of Thursday, December 15th 2016, this product now comes fully assembled! Plug in your Feather and you're ready to go immediately.

Technical Details

Some folks have noted that this breakout doesn't play well with Particle Boron, please add a 10K resistor on the EN line to make it work better.

Revision History:

  • As of Feb 5, 2020 - Adafruit have made the trace to the enable pin thicker, and added a ground plane which helps keep the enable line clean some high-noise environments.

Helpful microcontroller to use with the Pico Display pack. Does everything i need it to.

Brilliant device, not quite as fast as a Teensy but better price and more pinouts!

Great little device, very affordable with a really small footprint. Works perfectly for my project, powering a framed pico paper display.

A wonderful little device, and so cheap it's worth having a few kicking around so you can just act on ideas.

I have several Pi Pico boards with and without headers, but I thought I would try out the WH and save myself some soldering. It fits nicely in a breadboard and the little debug header is soooo cute!

I am using this for building a rain guage. I am very pleased that you can turn it into a Modbus slave using TCP IP in Micro Python and get the data off Wirelessly.

Haven't had any problems so far. The bluetooth and wifi works great as well. The test programs supplied by on the raspberry pi website worked.

Bought the first Pico W for a mesh radio project. The second to get back into 'electronics' and enjoying just having fun. Think I need a Pi 5 now to replace my ageing Apple computers. Good technology and understanding flows from just trying stuff out.

hopeing to use this with the Kitronik Autonomous Robotics Platform, to make a wirelessly controlable robot :) Also loving the micropython API for network comms.

Actually purchased one of these along with a WH version, also some pi debug probes. A great combo. Especially like that the integration of Pico WH + probe+platformIO is really good.

As ever, the RPi Pico W is great news for micrcontroller users. I used this one with Microblocks.fun to read the cheerlights colour and produce Neopixel colour patterns.

Really really good, it is brilliant for beginners to learn simple programming and amazing for anything above that.

Pico without the need to solder the headers on. Yes I can solder but factory made soldered joints are always better than hand soldered.

Great little device, I have connected temp and humidity sensor, light sensor and motion sensor to it and publishing through Matt to a server. All cheaper than buying one

Perfect for my project, simplified by the added header already attached. Pimoroni crew ensured super fast delivery too. All in all a great experience, I’m looking forward to my next one.

There's a few ways to program a RPi Pico. 1. Assembler 2. C/C++ 3. Micropython 4. Circuitpython (from Adafruit) 5. Methods I've not discovered yet I've found that Circuitpython is easiest and has the best scope for programming it. I got mine connected to my WiFi in less than an hour. Now I just need to find what to do with it next. It's a good

Not much left to say about this little slice of computer magic. Using mine to build a remote control for my garage door. Using HTML to check if the door is open or closed with a capacitive touch sensor to trigger the door motor. Micropython makes the coding really straightforward.

A little bit of effort to set up and use but fantastically powerful. I'm just running a simple clock with this, and I connect to a mobile hotspot to sync the time when it boots!

Have not tried it yet. At present still putting together the motherboard it will be fitted on. However, the design looks good and I look forward to setting the system up.

The Pico has now become even more awesome with the addition of wifi and bluetooth. The onboard chip is easy to program in Micropython and fast enough for any application. I was able to write some scripts that load the py files from a simple web server on boot. I can now use VS Code instead of Thonny and the communication is much more reliable than the serial.

Really good for its price, its powerful and can aid you with your project if you require Wi-Fi.

Easy ordering, quick delivery - what more can you want. As to the device; it's just so easy to get the examples running (including a couple using external I2C thingmebobs). I wired up the thingmebobs using wires and solder and it all worked fine even though I last soldered electronics back in the 80's at school. If you're into tinkering I would thoroughly recommend it.

Ypu can do so much more with a Pico when you have WiFi. Connects really fast to network on power up. Micropython has a few minor bugs as it's still being worked on but updates are daily as they improve the build. Still waiting for Bluetooth support but hear that's coming soon.

Works perfectly, Thonny IDE connects and works fine, micropython is fun to work with. The wireless chip definitely works, and now i can send magic packets for wake on lan to my PC. If only the LiPo shim was in stock, i could make a one button remote for my PC. The little plastic tray it came in is also useful to store it in when not in use, i haven't finalized the hardware to solder it into yet.

Can't beat the Pico for a cheap and powerful processor board with the added benefit of WiFi on board.

This is the first time using the W version, its really so much better to be able to use the wifi to make projects work using a web interface.

This is a great upgrade for my IoT projects, the PICO and PICO W are just great micros and are now very well supported on Arduino and PlatformIO IDE's - which are my preferred programming platforms under Linux.

Since 1991 I have used Microchip PICs in my industrial designs, but since coming across this powerful micro on a neat board, which is utter simplicity to use, I am now looking at using pico boards for my future projects. An excellent product together with a good range of accessories to promote experimentation and learning for people of any age. To simply say I am impressed is an understatement.
