Product Showcase: Arduino UNO R4 WiFi

Find it here: www.sparkfun.c...
The UNO universe expands with UNO R4 WiFi: the same industry-standard form factor at 5V operating voltage, but with the enhanced performance of a RA4M1 32-bit microcontroller by Renesas with ESP32-S3-MINI coprocessor - for increased computational power, memory and speed - as well as Wi-Fi® and Bluetooth® connectivity, a 12 x 8 LED matrix, and a Qwiic connector.

Finally. An actual hardware specification.

You can add wifi but not nrf24
Why??

[@tyttuut]

NRF24 is a lot less versatile.

[@Onlyindianpj]

@@tyttuut can you please explain a bit more

[@d_sanu]

What is the functionality of nrf24? (I use nrf52833 btw)

[@murek5572]

What os nrtf 12 ?

[@murek5572]

Nrf24*

[@dimitrioskalfakis]

how do the two controllers communicate with each other? can we program the esp32? can we use its ram?

[@tagalogelectronics6615]

Rob Reynolds is my idol...🤠🤠🤠

[@proof6930]

Can it be programmed from a usb 2 serial port?

[@MahBor]

Most likely yes

[@tetsujin_144]

The schematic for the board shows that the D+/D- data lines are the only ones connected. The TX/RX pairs used by "super-speed" USB 3 are not connected. So yes, it's a USB 2 device.

The Arduino board LED matrix... WHY/WTF?!!?!! Are we jumping the shark when it comes to LEDs?

[@tetsujin_144]

I think probably it was like a case of "why not?" - The new CPU has more I/O lines, so add a dollar worth of LEDs to the board and those I/O lines that would have been unusable now have a use.
If you don't want to use the LED matrix, don't use it. Or buy the R4 Minima version, save a bit of money and do without the LEDs, WiFi, and QWIIC port

Thanks, helpful. Did not however appreciate the ending advice to stay safe and be kind.
