DETAILED DESCRIPTION
It's now a DevDuino: https://www.kickstarter.com/projects/1799914219/devduino-the-best-way-to-learn-and-explore-arduino
[EN] Design Requirements
- Microcontroller: ATMega32u4 - It's a pretty good 8 bits µC.
- Connector: Type-C USB - Type-C USB connector can be plugged in both ways and I really like that even if they are more expensive.
- Power switch ON/OFF
- Display OLED 128x64 I2C 0.96" - I would love to have a nice OLED display to output some useful data instead of always be staring at the serial monitor.
- Low Power buffered LEDs on all DIO et ADC - It's always useful when you can quickly know the state on your I/O by just having a look on your board. (Not sure yet about the buffers, I am currently using Low Power LEDs so it shouldn't be a problem to take them off.)
- Mechanical requirements:
- Must be breadboard compatible (Note: some 830 breadboards have a different tipogology with the power lines)
- Headers should never hide the silkscreen like on an Arduino board - I want it to be instantly visible.
- USB connector must be on the on the top - so we can't be bothered by the USB cable.
- Must be possible to add some future custom modules inside the "bridge". (Poke-yoke required)
- Component: SMT as much as possible - PCB should be quite busy because of the tracks.
- 2 Layers PCB... at the moment...
- Prototype price: As cheap as possible!

[FR] Cahier des charges
- Microcontrôleur: ATMega32u4 - C'est un très bon microcontroleur
328 bits. (Merci Olivier!) - Connecteur: USB Type-C - Je n'aime pas me soucier du sens quand j'enfile un connecteur.
- Interrupteur ON/OFF
- Ecran OLED 128x64 I2C 0.96" - Ca serait vraiment top si je pouvais sortir des informations directement sur un petit écran au lieu d'utiliser la liaison série.
- LED basse consommation pour toutes les DIO et ADC - Ca serait parfait si je pouvais connaitre l'état de chacune de mes E/S d'un simple coup d'oeil.
- Contrainte mécanique:
- Compatible avec toutes les breadboard 830 points
- Les connecteurs ne doivent jamais cacher la sérigraphie.
- Le connecteur USB ne doit pas gêner
- La forme générale de carte doit permettre d'acceuillir des modules prochainements développés. (Détrompage nécessaire)
- Composants: CMS autant que possible - La carte sera très probablement dense et ça me permettra en plus de faire une vidéo pour vous expliquer comment souder par refusion.
- PCB2 couches... pour le moment...
- Prix du prototype: Le moins cher possible!
