Vertically Mounted Arduino-Compatible Board

Clovis Fritzen designed this Arduino-compatible, vertically-mountable board that exclusively uses through-hole components:

arduino-vertical-676x507

Vertically mounted Arduino for Breadboard

I personally love the concept of electronic boards connected in “slots” (vertically attached to a horizontal board), like most industrial-grade PLC’s or even our desktop’s expansion cards (video, sound memory): it saves a lot of space and adds more functions to the system, all at once!

 

The PCB is for sale on Tindie:

tindie-logo2x

Vertically mountable Arduino – PCB only

This is an Arduno-Nano compatible controller that can be vertically mounted to bredboards and boards

OnChip Open-V Arduino Compatibility

OnChip has posted a Crowd Supply update on their plans for Arduino compatibility:

Open-V Arduino Compatibility

Arduino compatibility can mean a lot of things to a lot of different people, so we’ll try to be as concrete and specific as possible. For the Open-V, Arduino development tools, and interoperating on a hardware level with existing Arduino shields.

We’ve updated our live, web-streamed demos to include an Arduino mode in addition to the assembler and C modes we already have. You might also notice the relatively new Blockly modes and a refined layout of the demo page. Go write some code and see the results live streamed!

Flight Controller:

STM32L432 receives quaternions from the EM7180, which itself is master to the motion and pressure sensors, GNSS data from the CAM M8Q, then processes and packages the data and sends it to the ESP8285 via UART bridge for transmission to a hand-held controller

Industrial Diagnostics:

uses an STM32L433 as master to several slave sensors to detect and process signals from industrial equipment and report to a remote server via blue tooth

Electro_pet by Facelesstech

I got inspiration for this project from the petduino. The petduino is a great project to get kids into coding and electronics. I thought I would have a go and see if I could add some more features to it. Also my daughter was really interested in the 8×8 led matrix

The MightyWatt: a 70W Electronic Load Kit

of Kaktus Circuits created this programmable electronic load that sits on top of an Arduino:

The MightyWatt: a 70W Electronic Load Kit

Electronic loads are used to draw power from a source at either a constant current or a constant voltage. This comes in useful for things like battery discharge testing or making sure that PCB you designed can actually power those motors without releasing the all important magic smoke.

The kit is sold on Tindie:

MightyWatt turns your Arduino Uno R3, Arduino Zero (M0/M0 Pro) or Arduino Due into an electronic load capable of dissipating 70 Watts in a very small form factor. Ideal for testing power supplies, batteries, fuel cells or power amplifiers.
