The P2 Edge Module is a simple way to get started with the Propeller 2 multicore microcontroller. In addition to speeding development, this module provides an optimal P2 building block for system integrators and designers to include in their products.

The Propeller 2 P2X8C4M64P chip contains over 32 million transistors and >70 mm2 of custom silicon, 10x that of a typical microcontroller. The P2 contains 8 independent processors with analog pad rings and Smart-pin functionality at all 64 I/O pins. Each smart I/O pin is capable of many autonomous analog and digital functions, including ADC, DAC, PWM, USB, SERIAL, Waveform generation, SMPS, Comparator, SCHMITT and LOGIC modes.

The P2 Edge Module includes the exposed-pad 100-pin TQFP P2X8C4M64P, core and I/O power regulators, power filtering capacitors, crystal, flash memory, boot configuration switches, and two user-configurable on-board LEDs to indicate system states. The PCB’s four-layer design features solid thermal and signal reference planes isolating each signal layer. The design is optimized for low-noise analog and digital operation, and with low temperature rise even at high-speed operation.

New features for Rev C include an onboard microSD socket, power supply VIN voltage maximum increased from 5.5 to 16 VDC, and the onboard clock source upgrade from a low-precision crystal to a high-precision TCXO oscillator.

For development, the P2 Edge Module fits in the card edge socket of the spacious P2 Edge Module Breadboard, the compact P2 Edge Mini Breakout Board, or the bare-bones P2 Edge 80-pin Adapter Kit. For product integration, several edge socket choices are available from our P2 Components shop page. This arrangement allows developers to integrate the Propeller 2 into products without the need for multi-layer cost or expertise.
