3D-Printed Adapter for Mounting ESP-12F Module with 2mm Pitch to Breadboard/Perfboard 0.1″ Spacing, with OpenSCAD Instrux | #3Dprinting #3DThursday @openscad
HydraRaptor’s design is for the ESP-12F module – not the -S version we sell in the shop – but nonetheless this is a great, simple mod for adapting devices and boards of various layouts.
I plan to make a few projects based around ESP-12F WiFi modules. These are postage stamp sized modules containing an ESP8266 chip plus 4MB of flash. The ESP8266 chip is a 32 bit MCU with an integrated WiFi transceiver and TCP/IP stack. They come programmed as a WiFi modem but they can be reprogrammed with the Arduino IDE to do other things in addition to the WiFi. Great for IOT applications because they are so small and cheap (less than £2) but reasonably powerful. A lot more powerful than an Arduino, for example, but with less I/O.
The solder pads are on a 2mm pitch, so they are often used with a breakout board to adapt them to 0.1″ pitch for breadboard or perfboard, etc. That adds cost and increases the size somewhat because the through hole pins need to be outside the perimeter of the module. I solved the problem another way, by using a 3D printed wire guide that routes wires from the 0.2mm pitch holes to the nearest 0.1″ hole, minimising the space used and costing virtually nothing.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
