2. Single board computers (SBC) Raspberry Pi (RPi), PINE A64, C. H. I. P
Single board computers (SBC) Raspberry Pi (RPi), PINE A64, C.H.I.P., Beaglebone, and others
Cost generally <$50
Most employ ARM 32-bit or 64-bit RISC processors
Run full-featured operating systems
GUIs and fully-developed applications available
Still have General Purpose I/O (GPIO) onboard
Onboard networking, USB, and storage (via SD cards) is very common
Low power requirements
Large open-source development community

3. Microcontrollers Arduino, STM32xx, Teensy, PICAXE, BASIC Stamp, and MORE!
Cost generally <$30
Generally utilize AVR, ARM, or STM32 processors
No OS and no traditional applications
Need a development environment (IDE) and a PC to program
Flexible, expandable, and customizable
Well-suited to embedded applications
Very low power requirements
Large open-source development community

4. What makes theM SO unique?
INTERFACES!
GPIOs (General Purpose Input/Output)
I²C (Inter-Integrated Circuit)
SPI (Serial Peripheral Interface)
…and many more!

5. Analog and Digital GPIO
Analog input to ADC (Analog to Digital Converter) Digital I/O Pulse Width Modulation (PWM) Interact with physical world!

6. Complex data exchange
Serial SPI (Serial Peripheral Interface) I²C (Inter-Integrated Circuit) USB Ethernet Interact with other devices!

7. A few Projects I’m working on…

8. And some inspiration for you…
ADS-B tracking system (RPi)
Echolink or DStar hotspot or node (RPi)
SDR (Beaglebone, RPi)
WSPR beacon (RPi)

9. And some inspiration for you…
APRS tracker (All SBCs, Arduino)
APRS digipeater or iGate (Most SBCs)
CW keyer (Arduino)

10. And some inspiration for you …
SWR/power meter (Arduino)
Remote CI-V connected antenna switch (Arduino)
Antenna rotator controller (Arduino)
