Hello Guys,
I'm designing custom shield and I would like to make it universal for as many arduino board as possible (and maybe somoe other platform BluePill, NodeMCU etc). My project is similar to ArduShield.
As far I covered UNO, MINI, PRO MINI and NANO.
I noticed that some of arduino boards have the same form factor and pinout and this is exactly what im asking for.
I would like to ask you if could me provide list of compatible boards (including most recent and fancy)?
All the information you’re asking for is in the public domain.
You do know the ardushield was a commercial failure, right?
You realise that some of the platforms you mentioned are 3.3V logic and some are 5v logic ?
A lot of the newer boards, not mentioned, will be 3.3v.
They are not going to be 'compatible'.
Boards that use the Uno form factor:
Uno WiFi Rev2
Leonardo
Yun
Arduino 101
The Mega and Due have a form factor that is compatible with the Uno's, but with extra pins.
The modern version of the Uno/Mega pinout has an IOREF pin that is intended to allow shields to detect the logic level of the board they are plugged into.
There are four new boards that use the same form factor as the classic Nano:
Nano Every
Nano 33 IoT
Nano 33 BLE
Nano 33 BLE Sense
The Arduino Micro has a form factor that is similar to that of the Nano.
The Pro Micro has a form factor that is similar to that of the Pro Mini.
Perfect is the enemy of good.
Current production technologies make it possible to produce things in low quantity while still getting amazing quality and low price. Make use of it and build different versions of your shield.
