Picture of NodeMCU breadboard tweak

I like to build and lab with electronics like Arduino and lately with the ESP8266. The NodeMCU is a development-kit with USB to serial and a ESP8266, model ESP12 mounted on a small PCB. And it is easily programmable via the Arduino IDE, you just have to add hardware support for it, see URL below.

Reference:

The challenge with NodeMCU is that there is no holes left on the solderless breadboards when you have mounted the Node MCU on it.

The solution is just 10 minutes away!

Step 1:

  • Hacksaw
  • File
  • Scissor
  • Clamp
  • Alcohol
  • Snap-Off Utility Knives
  • Work table with a vise

Haha this is great. I've been sitting here with different right angle and extra long pass through headers trying to come up with some elaborate way to reduce pin width. Then I log online and see your hacksaw photo. I remember thinking "Well that is just ridicu.... holy shit, this guy is a genius!" I was "this" close to literally start clapping for you in my chair. Keep up the good work!

I very like your tutorial. If you need the Nodemcu module in Canada, here is a good store to buy it : https://voltatek.ca/esp8266-nodemcu/200-nodemcu-v3-wireless-wifi-module-iot-esp8266-with-ch340-usb-serial-driver.html

Briliant idea

Destructive, yet with the small footprint, arguably the one of the best modifications. Thanks for sharing.

This is mine, no need to cut the board...

I had one long 60 pin board, now i've got two 30 pin board and one is separated for MCU. Thank you for idea!!

I'm not sure how so many people have missed this trick.
This is the reason why the breadboard has a "Breakaway" section in the middle of it.

Thanks for that brilliant idea! I always used NodeMCU V2 boards which left me with one row on each side and I was so annoyed about the V3 models I got recently! I used two breadboards till now, but your solution is much better!

I use 2 breadboards

I used that idea in the beginning, but the foot print was to large in my opinion.

Or you might use Croduino NOVA, which is almost the same as NodeMCU, but it is Breadboard compatible: https://www.tindie.com/products/dava_2/esp8266-with-usb-auto-reset-and-more-croduino-nova/

But then you get into a totally different price range.

NodeMCU + solderless breadboard = 5-6 USD

Croduino NOVA = 20 USD

excellent idea!

Cutting the bread board is. Very good idee. Thanks

One of those ideas, when you see it, you say "So simple, so obvious, why didn't I think of it before?".

Really genious!

Lol, awesome! Could you accomplish the same thing if you just put two breadboards side-by-side? That way you wouldn't have to cut up your breadboards. :)

matsk (author)  michaelnelson3 years ago

I did that in the beginning, but the footprint from two breadboards was to big and I was missing the power-rails on the sides!
So that was the inspiration for the hacksaw, and a the cost for a solderless breadboard was just below 3$, so ...

thanks alot for sharing :)

Thanks for this one! Now why didn't I think of it! This also solves the issue I've had with the Adruino Fio and the Adafruit Huzzah ESP8266 with "not enough holes". Time to dig out the hacksaw.

That is a really clever idea. This would make your breadboard compatible with a lot more parts.

Thx. Now I just have to find out how to get rid of the constant rebooting of the NodeMCU.
