Serial4: This channel is optionally available via the Electron and E Series C3(TX) and C2(RX) pins. To use Serial3, add #include 'Serial3/Serial3.h' near the top of your app's main code file. It optionally supports hardware flow control. Serial3: This channel is optionally available on the P2 and Photon 2 only. To use Serial2, add #include 'Serial2/Serial2.h' near the top of your app's main code file. On the Argon and Boron, the hardware port is used to communicate with the network coprocessor (NCP) and is not available for user use. Since you supply your own LEDs on these devices, you can move them to other pins using RGB.mirrorTo(). On the P1 and E Series, this channel is shared with the RGB Green (TX) and Blue (RX) LED pins. As there are no test pads for these LED pins on the Electron, Serial2 will be difficult to use. If used for Serial2, the LED or current limiting resistors should be removed. On the Electron, this channel is shared with the RGB Green (TX) and Blue (RX) LED pins.

If the user enables Serial2, they should also consider using RGB.onChange() to move the RGB functionality to an external RGB LED on some PWM pins. The Blue and Green current limiting resistors should be removed. These pins are accessible via the pads on the bottom of the PCB See PCB Land Pattern. On the Photon, this channel is optionally available via pins 28/29 (RGB LED Blue/Green). It uses the same pins as SPI1, so you can only use Serial2 or SPI1, not both. Serial2: On the P2 and Photon 2, this channel is available. Serial3 uses the RTL872x LP_UART peripheral.Serial2 uses the RTL872x HS_UART0 peripheral.

Serial1 uses the RTL872x UART_LOG peripheral.Hardware flow control is optional if not used then the RTS and CTS pins can be used as regular GPIO.The UART pins are 3.3V and must not be connected directly to a RS-232C port or to a 5V TTL serial port.Gen 3 Devices (B Series SoM, Tracker SoM, Tracker One, Boron, Argon, and E404X):ĭ10 GPIO, Serial 3 CTS, WKP. Serial1: This channel is available via the device's TX and RX pins. Since Serial.print is not thread safe, it can interfere with the use of Log calls. You should also avoid mixing the use of Serial.printlnf and Log.info (and similar calls). It also allows log messages to be intercepted by code, and even saved to things like SD cards, with additional libraries. Using the Log method makes it easy to switch between Serial and Serial1 (or both!) as well as providing thread-safety. Instead of using Serial directly, you should use it using the the SerialLogHandler if you are writing debugging messages. Serial: This channel communicates through the USB port and when connected to a computer, will show up as a virtual COM port.
