So, I trust that many here get the emails from Microchip concerning their monthly sales. This month, one of the sale items is their ATmega4809 board on sale for US$7.50.
This reminded me that I bought a couple the last time that they were on sale. I can't help myself sometimes. I like boards. Especially when they are cheap and interesting.
I really have done very little with it...so far. One thing I did do was to load the Arduino Core that this fellow has written. It is really quite cool. Turns it into a familiar Arduino and programmed with the familiar Arduino IDE. It is a work in progress, but it is up and running.
Why bother with a $7.50 Arduino board when you can get "real" clones for $2? Well, I am not going to try to sell that case, but note that it is a 20MHz board. In fact, you can program the board clock speed (1-20Mhz). (at compile time, I don't know about inside of a program, but I might have remembered some of that messing around with it in MPLABXIDE - maybe not).
I also have not done a side-by-side comparison, but the 4809 does seem to have a lot of I/O and 3 UARTS. The board has a debugger and some other interesting features....could be useful.
