- Features:
- The Parallax Propeller II MCU (P2) with 8 cores and 512 kB of internal RAM and 64 Smart I/O Pins
- Integrated FTDI USB serial interface for
programming and debugging via Micro USB connector (also supplies up
to 500 mA of power)
- VGA output directly from P2 pins
- Dual USB interface for keyboards, mice,
game controllers, etc.

array of SparkFun and Adafruit items)
- I/O pins P0..P7 brought out to a Eval
style connector for use with several Parallax Eval Board Accessories
- A barrel connector for 6..9 VDC input to
5 V regulator for extra power
- A Propeller Platform style header for I/O
pins P24..P51 and also GND, 3.3 VDC, 5.0 VDC, and VIN
- Pads to optionally add up to 64 MB of
PSRAM on bottom of board.
- Four blue LEDs, two normally used for USB
status, and two shared with Qwiic connector I2C pins

- Notes on
Overclocking (running over 300 MHz)
- Some SimpleP2++ boards can overclock more
than others, for this reason they are binned into two speed classes.
- Speed Class1: Can
all run at 320 MHz (tested with the emulator program MegaYume)
- Speed Class2: Can
all run at 340 MHz (tested with the emulator program NeoYume)
- The ability to run overclocked depends on
several factors including power supply, room temperature, and cooling.
- Forced air cooling (fan) may be required to
run for more than a few minutes
