However, Arduino ... (3.3V, 5V, and VIN). Their onboard LEDs are connected to pin D13, and their serial RX/TX pins are on pins D0 and D1, respectively. Additionally, the Nano and Micro feature 20 ...

PD Micro is the first ... board only outputs 3.3 or 5 V – such as those involving motor control or high-power LEDs. The output voltage can be controlled with Arduino sketches using our new ...

While the pinout is very similar to the Arduino Nano’s, there are four (12-bit) analogue inputs rather than eight (10-bit). Some digital ... GPIO pin 20.” “On either side of the micro ...

Update April 2022: also works on clone of SparkFun Pro Micro (except no LED-BUILTIN is fitted) End Update Here is ‘blink’ modified to work TXLED and RXLED as well as LED-BUILTIN int RXLED = 17; // The ...

Microduino’s new generation of little stackable Arduino modules ... And their unique 27 pogo pin setup keeps damage to a minimum when you stack the modules. And, of course the little circular ...

Well, say no more, as [Nick Poole] has you covered with his insane RedBoard Pro Micro-ATX ... a variation of the standard Arduino “shield” concept using 28 pin edge connectors.

Microduino actually isn't the smallest Arduino clone on the market. The Femtoduino, boasting the "same power and pin count of an Arduino Uno," measures just 0.81" × 0.6".

[MakinStuff] wrote in to let us know about a project he did for new and improved interfacing to the ubiquitous cheap Chinese digital calipers ... driven sample Arduino sketch to read the data.
