Parallax P2 Edge Module - Datasheet

Hardware Connections

Minimal Connections

The Propeller 2 is programmed via four wires and may optionally include an external crystal, reset switch, SPI

Flash and/or microSD memory.

Minimal Propeller 2 Connections

● All VDD pins must be connected to a single 1.8 V supply.

● All Vxxyy pins must be connected to 3.3 V. The Vxxyy pins can share a common 3.3 V supply, or be split

across multiple supplies. Typically those Vxxyy pins powering analog and digital functions would have

different supplies.

● All VDD and all Vxxyy pins must have closely-located bypass caps to GND (not shown).

● The common GND (EP) pad under the chip is also used for thermal dissipation. It is recommended to

connect the GND pad to a solid ground plane with multiple vias.

● TEST pin must always be connected to GND.

● RESN (reset) pin must always have a pullup resistor to 3.3 V (typically 10 KΩ).

● Programming and debugging is achieved with a serial interface, such as the Parallax PropPlug #32201.

● Minimal connections assume no external clock source connected to XI/XO– the internal clock must be

used (adjust source code to match). Refer to the AC Characteristics table for further information.
