2.2. Sourcing

1

The Microchip ATMega328p is widely available from electronics component stores. Be sure to order the 28 SPDIP package in order to make it easy to insert the chip into a breadboard.

3

There are many USB ISP programmers available, but the exact model used in this book is the DFRobot USBtinyISP - Arduino Bootloader Programmer.

4

The FTDI LC234X USB ↔ USART adapter is widely available from electronics components stores. Any USB ↔ USART adapter will be usable and they are largely interchangeable.
