Uno R4 on a breadboard... bootloading and Hardware

Official Hardware UNO Family UNO R4 Minima

Having spent ages with the Atmel Uno and 328 chips I must say the R4 is a blast! Wow, so cool!

Now I already run into a project which I would like to professionalize and make it ready for automotive.

Two ways:

Just buy a R4 minima and make a shield or piggy back. Thats right, but it does not look good and also has some dowsides regarding space and safety

The old way: do you remember Arduino on breadboard- great fun! And i think this MCU looks perfect for such endeavors, but I could not find everything to convince myself to dare it.

Do you know how minmal the renesas can be connected?

And how to get a RA4 from anywhere to be able to speak Arduino? Maybe there is such a page as there was before with the breadboard? Or maybe a smaller devkit? Like the nano with the RA4?

Hi @BetaCarotin.

You are in luck! Arduino just released the Nano R4 board:

This board, uses the same Renesas RA4M1 microcontroller as the Minima, and with the same level of support from the Arduino ecosystem as the Minima, but in the compact and breadboard friendly Nano form factor:

That is mighty!

I think its the best way to just plan for two header rows on a PCB and solder it in place, very very nice!

Or even better, put a socket on the PCB and plug in the Nano just in case you need to change it for any reason
