Elektor Uno R4
Elektor Labs
Mfr. Part #
Product Description

This board is an evolution of the Arduino Uno R3 board. Identical form factor as the Uno but based on the ATmega328PB-AU (note the 'B'!), this board has much more features than the Uno. Because it is backwards compatible you can think of it as revision 4 of the Uno, which is why we called it the R4.

The circuit of the R4 is pretty close to the Uno. One of the main differences is the USB-to-serial converter for which an FTDI chip is used instead of another AVR. This saves on firmware/driver maintenance & device programming. The power supply is a bit stronger than on the Uno and of course four extra connector pins have been provided to accomodate Port E of the ATmega328PB.

How it works

This is a group buy campaign that needs to acquire at least the stated minimum amount of pledges from backers like you before the Unit Deliverable and any Add-Ons ship. We do not charge anyone until the Progress above hits 100% or greater, otherwise there is no charge. All campaign products are vetted as existing and functional so your order will be fulfilled within the Factory Lead Time if the campaign succeeds.
