ESP8266 breadboard adapter board

Markus designed a single-sided ESP-12/ ESP-07 breadboard adapter PCB: Features are: – Fits ESP-12 and ESP-07 module – Single-sided self-etchable design – Few, cheap parts in SMD – Breadboard-style – one row on each side accessible – Vin >4.5V (max. 7V) input possible with 3V3 onboard voltage regulator (with two capacitors 10µF) – Power-indicator LED […]

ESP8266 Breadboard adapter

Baoshi of DigitalMe wrote an article detailing his ESP8266 (ESP-07/12) Full I/O Breadboard adapter, that is available at Github: The rise of the ESP8266 WiFi chip was almost overnight with Espressif’s open approach and pushing from Hackaday. While no ground-breaking product has yet emerged, the development on the chip are phenomenon. However due to an unknown reason the […]

Experimenting with buck DC/DC converters

Mike wanted to build a DC-DC buck converter. He didn’t stop at building one, he wanted to perfect it. So he built it on a breadboard and started experimenting. By exchanging various components and watching a scope for results, he was able to get the results he was looking for. The buck converter takes a […]

Roundup of tips and tricks for breadboards

Breadboards are a really helpful tool for quick prototyping. Boseji made a roundup of breadboard tips and tricks available online. His article includes useful tips like how to breadboard a power supply, and even how to build one yourself. We have all used breadboards, or those who plan to jump into the fascinating world of […]

Bus Pirate to breadboard cable hack

Joe Desbonnet writes that he’s found a quick and cheap Bus Pirate to breadboard cable hack. “I needed to check out a I2C temperature/humidity sensor with the Bus Pirate on a breadboard. So I hacked this connector comprising a short length of 10 wire ribbon cable, a 5×2 IDE connector to mate with the BusPirate […]

Breadboard limitations

We love breadboards, they make prototyping easy, but they have their limitations. The way breadboards are built imposes a low maximum frequency to the design, typically  less then 50 MHz.  This is due to the high parasitic inductance and capacitance on solderless breadboards. For designs that work at low frequencies, breadboards are the ideal tool […]

nedoCPU-16: PIC16F87X breakout board

Here is a breakout board for the PIC16F87X microcontrollers. It has a onboard 5V power supply, a 20MHz crystal, and a reset button, while all the IO pins have been broken out into a single row header, so its easy to interface with a breadboard.The UART and ICSP programing header have been broken out on […]

DIY breadboard modules for rapid prototyping

Raj made a few breadboard modules to speed up prototyping. We think it’s a great idea to have a power supply, few switches, LEDs, etc, broken out into modules. It will save you a ton of time, and space on your breadboard. Breadboards are a great tool for prototyping and testing electronics circuits. However, if […]

How-to use surface mount parts with a breadboard

Pppd shared a tip for using surface mount parts with a breadboard, mount them on 0.1″ pin header: Also, I’m probably not the first one to do it this way… but if you don’t like through-hole parts just as much as I hate them you may want to use surface mount resistors, capacitors or even […]

Bus Pirate breadboard probe cable

Zbig shared his approach to the breadboarding cable for the Bus Pirate. I use single pins soldered to the cables and secured with some shrink tube. I make the labels with Brother P-Touch label maker on a special flexible tape (TZ-FX series). Get your own handy Bus Pirate for $30, including world-wide shipping. Also available […]

VirtualBreadboard 4.3.3

VirtualBreadboard 4.3.3 is a Windows GUI program that lets you simulate and develop embedded applications that use microcontrollers. It essentially lets you assemble virtual components on screen and auto generate code. Currently some Microchip PIC16 and 18 devices are supported, as well as Arduino. In addition a wide variety of simulated components such as LCD’s, […]
