P2 Edge Module Breadboard (#64020)

The Propeller 2 Edge Module Breadboard provides a convenient rapid prototyping solution for

experimenting and developing with the Propeller 2 microcontroller.

Multiple breakout headers, ground points and a large breadboard are included for simpler

testing and interfacing with standard test equipment.

The board accepts the P2 Edge Module (#P2-EC) and includes the supply voltage DC Jack socket,

Parallax Prop Plug (#32201) programming socket, reset button and power switch with indicator

LED.

All of the P2 Edge I/O’s are available at 0.1” pin header sockets around a large breadboard.

There are eight servo-style ports compatible with a range of Parallax servos and sensors, and

eight P2 accessory headers, compatible with both single and dual header Propeller 2

accessories, including the mikroE Click adapter providing developers with connectivity to over

900 different Click modules for rapid development.

The P2 Edge Module Breadboard is compatible with a wide range of modules, adapters and

accessories. See the Propeller 2 section of the Parallax web store at www.parallax.com for

options.

1. Parallax P2 Edge Module Socket The P2 Edge Module socket is a 0.05” (1.27 mm) pitch 80-way vertical socket. Refer to the Edge Connector Pin Assignment in the P2 Edge Module product guide for full details. It is available for download from the P2-EC product page at www.parallax.com. The P2 Edge Module must be inserted with the component side facing the breadboard. There are silk-screen text markings beside the socket to indicate the positions of P0 and P38.

. Servo Headers The servo ports connect servos and other 3-pin devices to the 0.1” pin sockets positioned alongside each port, so that the signals can be jumpered to the breadboard or directly to a P2 Edge I/O pin. In the image example, we can see servo port 5 on the right. The pinout follows the Parallax standard BRW cable color scheme (Black-Red-White). The top pin connects to Ground (Black wire). The middle pin connects to 5V, directly from the DC Barrel Jack (Red wire).

300 mA total). If a larger current common supply is required, add an alternative power source to the breadboard, such as the Parallax Power Pal (#32133). 6. P2 Edge I/O Pin Access Access to the P2 Edge Module smart I/O pins P0...P63. Use jumper wires to connect these I/O pins to circuits on the breadboard. In the above image, the I/O pins are labelled 48 to 55. 7. Breadboard The breadboard area has dual 30 x 5-socket rows arranged in 2 columns, for a total of 60 rows.

12. I/O Pin Accessory Headers (with 5V output) Each of the 64 smart I/O pins is connected to an accessory header, in specific groups of eight. Each edge header also provides two GND connections, a Vxx output pin supplying the voltage from the corresponding 3.3 V LDO voltage regulator, described above in VIO 3.3V Power and GND Access, and optionally a 5 V output connection (controlled by the ACC ON/OFF Header). There are two special usage edge header banks which do not supply the 5V output.

Edge Connector Pin Assignments Smart I/O pins P0–P55 are fully free; P56–P63 are routed to peripheral circuits and/or have special functions related to Propeller 2 boot sequence options. Each smart I/O pin is capable of many autonomous analog and digital functions. Examples include ADC, DAC, PWM, USB, SERIAL, Waveform generation, SMPS, Comparator, SCHMITT and LOGIC modes. See the Propeller 2 Documentation section of www.parallax.

Other Pins Description Internally pulled up to 3.3V with 10K resistor. RESn Propeller chip will reset when RESn driven low; all cogs disabled and I/O pins floating. Propeller restarts 3 ms after RESn transitions from low to high. Power input pins for the Edge Module. Connect both 5V edge connector pads to a good quality 5VDC supply. The supply voltage MUST NOT exceed 5.5V! 5V Recommended minimum supply current 100mA, up to 3A depending on customer code and circuit.
