Arduino Pro Mini

Inexpensive and widely available
Arduino Pro Mini Schematic
I/O - 14 digital input/output pins (of which 6 can be used as PWM outputs)
- Serial: 0 (RX) and 1 (TX).
  - Used to receive (RX) and transmit (TX) TTL serial data.
  - These pins are connected to the TX-0 and RX-1 pins of the six pin header.
- External Interrupts: 2 and 3.
  - These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
  - See the attachInterrupt function for details.
- PWM: 3, 5, 6, 9, 10, and 11.
  - Provide 8-bit PWM output with the analogWrite function.
- SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK).
  - These pins support SPI communication, which, although provided by the underlying hardware.
- LED: 13.
  - There is a built-in LED connected to digital pin 13.
  - When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
- 6 analog inputs
On-board resonator (8 or 16 MHz)
Reset button
A six pin header can be connected to an FTDI cable provide USB power and communication to the board
3.3 or 5V
8 MHz (3.3V) or 16 MHz (5V)
Programmable in Arduino IDE

Detachable Human Interface design (HID)

Can leave attached to main board until installing in box

Input Power Options

2.1mm DC Power Connector Jack

  - 5-23V (for 3.3V Arduino Pro Mini)
  - 7-23V (for 5V Arduino Pro Mini)
  - About $1
Jumper to use raw input and not populate the Mini360
- Uses the inputs jack as RAW power into the Arduino Pro Mini
- 3.35-12 V (3.3V model) or 5-12 V (5V model)

I/O Boards

Base board has 3 optional BNC (P1-P3) or edge launch SMA (P4-P6) connectors
- Brought to headers (J4, J7, J8)
Easy to application specific custom I/O cards
- All Arduino pins brought to J5 - 2x13 pin header
- I/O pins are on 0.1" grid for easier prototyping

Test

Test code - OLED/Rotary Switch Test
If there is no display on OLED, verify OLED appears at expected I2C address with I2C scan at I2C address 0x3C
- Expect results

Scanning...

done

May require a different constructor
- I used

Total Memory usage with u8x8 Library and Rotary Encoder Code

OLED/Rotary Switch Test
Arduino bootloader uses up 2048 bytes of Flash

Sketch uses 7062 bytes (22%) of program storage space. 
Maximum is 30720 bytes.
Global variables use 475 bytes (23%) of dynamic memory, 
leaving 1573 bytes for local variables. Maximum is 2048 bytes.

Minimal u8x8 code

Sketch uses 6198 bytes (20%) of program storage space. Maximum is 30720 bytes. Global variables use 446 bytes (21%) of dynamic memory, leaving 1602 bytes for local variables. Maximum is 2048 bytes.
