Running out of space in your big Arduino project? Good news! Finally, after months of backorders, one can now buy the latest improvement to the ‘ATmega8′ line of chips: the ATmega328′s.
The ’328 has 32K of flash, and 2K of SRAM. Basically its got the capacity of an ATmega32 but in a slimmer package. These chips are notable for their ability to drop-in replace the ATmega168. So that means if you have an Arduino or compatible clone, it is a easy 2 minute swap.
I’ve merged my previous updates to the Arduino bootloader to the most recent release and also fixed 2 annoying bugs that have prevailed this long. (1. the missing signature bytes when using the bootloader directly and 2. the broken EEPROM code). Download the ’328-compatible bootloader files here.
There are 250 preprogrammed chips are in the Adafruit webshop or you can get blank chips from Mouser (but be warned that they’re backordered till mid-December)Related
