RF

  • The P2 includes an on-module PCB trace antenna and a U.FL connector that allows the user to connect an external antenna.
  • The antenna is selected in software. The default is the PCB trace antenna.
  • The area surrounding the PCB antenna on the carrier PCB should be free of ground planes and signal traces for maximum Wi-Fi performance when using the trace antenna.
  • Device operation in the 5150-5250 MHz band is only for indoor use to reduce the potential for harmful interference to co-channel mobile satellite systems.

SWD/JTAG

The P2 module supports programming and debugging use SWD (Serial Wire Debug) on pins D6 and D7.

Pin JTAG MCU Pin P2 Pin # Pull at boot
D7 SWDIO PA[27] 54 Pull-up
D6 SWCLK PB[3] 55 Pull-down
3V3 Power
GND Ground
RST Reset

When the bootloader starts, for a brief period of time a weak pull-up is applied to pin D7 and pull-down to pin D6 to detect whether a SWD debugger is attached. After boot, you can use these pins for regular GPIO, but beware of a possible GPIO state change caused by the pull-up or pull-down when using these pins as output.

Note that SWD is shared with GPIO pins D6 and D7, and by default SWD is only enabled while the bootloader is running, immediately at boot, and when in DFU mode (blinking yellow). Only Debug builds in Particle Workbench have SWD enabled in when user firmware is running.

Flash Layout Overview

Address File Purpose
0x00000000 p2-prebootloader-mbr This file is factory configured and must never be overwritten
0x00004000 p2-bootloader Device OS bootloader
0x00014000 p2-prebootloader-part1 Bootloader for KM0 processor, infrequently modified
0x00060000 p2-system-part1 Device OS system part
  • The location of the user binary is dependent on the size of the user binary and is not flashed to a fixed location.

  • Do not chip erase the RTL872x under any circumstances! Also do not flash anything to address 0 (prebootloader-mbr). The prebootloader-mbr is factory configured for your specific device with the private keys necessary for secure boot. If you erase or overwrite this portion of the flash you will not be able to program or use the device again.

DCT Layout

[This information is from the P1, and is likely to remain the same, but is subject to change.]

The DCT area of flash memory has been mapped to a separate DFU media device so that we can incrementally update the application data. This allows one item (say, server public key) to be updated without erasing the other items.

DCT layout in release/stable found here in firmware.

Note: Writing 0xFF to offset 34 (DEFAULT) or 3106 (ALTERNATE) will cause the device to re-generate a new private key on the next boot. Alternate keys are currently unsupported on the P1 but are used on the Electron as UDP/ECC keys. You should not need to use this feature unless your keys are corrupted.

  • If not using a SPI port, its pins can be used as GPIO
  • Any pins can be used as the SPI chip select
  • Multiple devices can generally share a single SPI port
  • SPI uses the RTL872x SPI1 peripheral (25 MHz maximum speed)
  • SPI1 uses the RTL872x SPI0 peripheral (50 MHz maximum speed)

I2C

The P2 supports one I2C (two-wire serial interface) port.

Pin Pin Name Description Interface MCU
35 D1 / A4 D1 GPIO, PWM, I2C SCL, A4 Analog In Wire (SCL) PB[5]
36 D0 / A3 D0 GPIO, PWM, I2C SDA, A3 Analog In Wire (SDA) PB[6]
  • The I2C port is 3.3V and must not be connected directly a 5V I2C bus
  • Maximum bus speed is 400 kHz
  • External pull-up resistors are required for I2C
  • If not using I2C, pins D0 and D1 can be used as GPIO or analog input.

PWM

The P2 supports PWM (pulse-width modulation) on the following pins:

Pin Pin Name Description MCU
23 A5 / D14 A5 Analog in, GPIO, PWM. PB[4]
35 D1 / A4 D1 GPIO, PWM, I2C SCL, A4 Analog In PB[5]
36 D0 / A3 D0 GPIO, PWM, I2C SDA, A3 Analog In PB[6]

41 S1 / D16 S1 GPIO, PWM, SPI MISO, Serial3 RX. (Was P1S1 on P1.) PA[13]
49 A2 / D13 A2 Analog in, PWM, GPIO PB[7]

All available PWM pins on the P2 share a single timer. This means that they must all share a single frequency, but can have different duty cycles.

USB

The P2 supports a USB interface for programming the device and for USB serial (CDC) communications. The module itself does not contain a USB connector; you typically add a micro USB or USB C connector on your base board. It is optional but recommended.

Pin Pin Name Description MCU
61 USBDATA+ USB Data+ PA[26]
62 USBDATA- USB Data- PA[25]

RGB LED

The P2 supports an external common anode RGB LED.

One common LED that meets the requirements is the Cree CLMVC-FKA-CL1D1L71BB7C3C3 which is inexpensive and easily procured. You need to add three current limiting resistors. With this LED, we typically use 1K ohm current limiting resistors. These are much larger than necessary. They make the LED less blinding but still provide sufficient current to light the LEDs. If you want maximum brightness you should use the calculated values - 33 ohm on red, and 66 ohm on green and blue.

A detailed explanation of different color codes of the RGB system LED can be found here.

The use of the RGB LED is optional, however it is highly recommended as troubleshooting the device without the LED is very difficult.

Pin Pin Name Description MCU
29 RGBR RGB LED Red PA[30]
31 RGBB RGB LED Blue PB[22]
32 RGBG RGB LED Green PB[23]

Boot mode pins

These pins have a special function at boot. Beware when using these pins as input as they can trigger special modes in the MCU.

Pin Pin Name Description MCU
54 D7 SWDIO. 40K pull-up at boot. Low at boot triggers MCU test mode. PA[27]
55 D6 SWCLK. 40K pull-down at boot. PB[3]
64 TX / D8 Low at boot triggers ISP flash download PA[7]

SETUP and RESET button

It is highly recommended that you add MODE (SETUP) and RESET buttons to your base board using momentary switches that connect to GND. These are necessary to change the operating mode of the device, for example to enter listening or DFU mode.

Pin Pin Name Description MCU
34 RST Hardware reset. Pull low to reset; can leave unconnected in normal operation. CHIP_EN
46 MODE MODE button. Pin number constant is BTN. External pull-up required! PA[4]

The MODE button does not have a hardware pull-up on it, so you must add an external pull-up (2.2K to 10K) to 3V3, or connect it to 3V3 if not using a button.

The RST pin does have an internal weak pull-up, but you may want to add external pull-up on that as well, especially if you use an off-board reset button connected by long wires.

BLE (Bluetooth LE)

BLE Central Mode on the P2 and Photon 2 is only supported in Device OS 5.1.0 and later. Earlier versions only supported BLE Peripheral Mode.

Product handling

Moisture sensitivity levels

The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required. The P1 module is rated level 3. In general, this precaution applies for Photons without headers. When reflowing a P1 directly onto an application PCB, increased moisture levels prior to reflow can damage sensitive electronics on the P1. A bake process to reduce moisture may be required.

For more information regarding moisture sensitivity levels, labeling, storage and drying see the MSL standard see IPC/JEDEC J-STD-020 (can be downloaded from www.jedec.org).

ESD Precautions

The P1 module contains highly sensitive electronic circuitry and is an Electrostatic Sensitive Device (ESD). Handling a P1 module without proper ESD protection may destroy or damage it permanently. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates P1 modules. ESD precautions should be implemented on the application board where the P1 module is mounted. Failure to observe these precautions can result in severe damage to the P1 module!

Default settings

The P2 module comes pre-programmed with a bootloader and a user application called Tinker. This application works with an iOS and Android app also named Tinker that allows you to very easily toggle digital pins, take analog and digital readings and drive variable PWM outputs.

The bootloader allows you to easily update the user application via several different methods, USB, OTA, Serial Y-Modem, and also internally via the Factory Reset procedure. All of these methods have multiple tools associated with them as well.

You may use the Particle Web IDE to code, compile and flash a user application OTA (Over The Air). Particle Workbench is a full-featured desktop IDE for Windows, Mac, and Linux based on VSCode and supports both cloud-based and local gcc-arm compiles. The Particle CLI provides a command-line interface for cloud-based compiles and flashing code over USB.

Intended applications

The P2 module is intended to be used for Wi-Fi based Internet-of-Things (IoT) applications such as environment, weather, HVAC, equipment, and security monitoring.

The P2 is not certified for use as a wearable device.

D Pin Change (2022-02-25)

The names of pins D9 - D22 have been changed to D8 - D21, eliminating the odd situation where there was previously no pin D8. This prevented being able to use a loop to initialize pins. This should not affect the hardware in any way, but software that used the D pin names instead of their more common names like TX (was D9, now D8) would need to be updated.
