|-
| VIN ||This pin can be used as an input or output. As an input, supply 3.6 to 5.5VDC to power the Photon. When the Photon is powered via the USB port, this pin will output a voltage of approximately 4.8VDC due to a reverse polarity protection series schottky diode between VUSB and VIN. When used as an output, the max load on VIN is 1A.
|-
| RST ||Active-low reset input. On-board circuitry contains a 1k ohm pull-up resistor between RST and 3V3, and 0.1uF capacitor between RST and GND.
|-
| VBAT ||Supply to the internal RTC, backup registers and SRAM when 3V3 is not present (1.65 to 3.6VDC).
|-
| 3V3 ||This pin is the output of the on-board regulator and is internally connected to the VDD of the WiFi module. When powering the Photon via VIN or the USB port, this pin will output a voltage of 3.3VDC. This pin can also be used to power the Photon directly (max input 3.3VDC). When used as an output, the max load on 3V3 is 100mA. NOTE: When powering the Photon via this pin, ensure power is disconnected from VIN and USB.
|-
| WKP ||Active-high wakeup pin, wakes the module from sleep/standby modes. When not used as a WAKEUP, this pin can also be used as a digital GPIO, ADC input or PWM.
|-
| D0~D7 ||Digital only GPIO pins.
|-
| A0~A9 ||12-bit Analog-to-Digital (A/D) inputs (0-4095), and also digital GPIOs. A6 and A7 are code convenience mappings, which means pins are not actually labeled as such but you may use code like analogRead(A7). A6 maps to the DAC pin and A7 maps to the WKP pin.
|-
| DAC ||12-bit Digital-to-Analog (D/A) output (0-4095), and also a digital GPIO. DAC is used as DAC1 in software, and A5 is a second DAC output used as DAC2 in software.
|-
| RX ||Primarily used as UART RX, but can also be used as a digital GPIO or PWM.
|-
| TX ||Primarily used as UART TX, but can also be used as a digital GPIO or PWM.
